EFFICIENT AND EQUITABLE HOUSING ALLOCATION
Since beginning his journey in the department of Industrial and Systems Engineering, Assistant Professor Nick Arnosti has showcased his passion for humanitarian research Most recently, Professor Arnosti has been awarded the U S National Science Foundation (NSF)
CAREER Grant This 5-year award will allow Arnosti to research the efficiency and equitability of the housing programs in the United States. His proposal specifically focuses on four topics related to housing allocationhousing voucher issuance, housing voucher portability and exchange, applicant prioritization, and policies intended to reserve assistance for particular applicant groups
For Arnosti, this research poses theoretically interesting problems that can be impactful to so many in need of housing With the goal of using the resources already available to the housing authorities instead of creating new ones, his research focuses on two goals that are often invoked but rarely defined: efficiency and equity. In seeking to achieve these goals, he looks to learn from current systems in other domains such as school choice, medical residency matching, and organ allocation
An Interest Begins
Arnosti’s interest in affordable housing allocation began when he was a professor at Columbia University He and his coauthor Peng Shi (University of Southern California), Marshall School of Business) were interested in analyzing the housing lotteries in New York City Their paper “Design of Lotteries and Wait Lists for Affordable Housing Allocation" notes that applicants have an incentive to apply to as many buildings as possible, and to take whatever they are offered Those who are lucky enough to win an apartment have little say in where they end up Arnosti and Shi show that the outcomes from this lottery are equivalent to those that would result from operating a waiting list in which applicants get a single offer, and those who reject this offer are moved to the back of the list. By allocating apartments with little regard for family preferences, these systems are wasting a precious resource. Arnosti and Shi examined several alternatives designed to grant applicants more say over where they will live.
This work by Arnosti and Shi focused on housing created through New York’s “Inclusionary Zoning” laws, and on federal public housing. Arnosti’s proposal seeks to study some of the many other programs that provide affordable housing to those in need.
Housing Choice Vouchers
One of the programs in Arnosti’s proposal is the housing choice voucher program, which provides rental assistance to approximately 2 million households The federal government provides the funding for this assistance, but vouchers are awarded and managed by thousands of local housing authorities
Housing Voucher Issuance
Once a voucher is provided, the voucher recipient must find a landlord who is willing to rent to them This can be challenging due to factors in the recipient’s past (such as poor credit or past evictions), and stigma by landlords against voucher recipients Exacerbating this problem is that vouchers are typically issued for a limited term (often 3-4 months) If a participant cannot find housing within this time frame, the voucher is taken away and given to someone else
This policy is intended to maintain high voucher utilization: a voucher being reserved for an applicant does no good to anyone while the applicant searches. However, a consequence of this policy is that applicants who have the greatest difficulty finding housing on the rental market are less likely to benefit from the voucher program.
“People should have an equal chance,” Arnosti explains, “but can only benefit if they can find housing Those who can’t will struggle This is a source of bias which is not the fault of the housing authority, but is exacerbated by the policy of taking away vouchers after a period of unsuccessful search ”
Arnosti proposed an alternative, which would allow people to continue searching for as long as they need To maintain high utilization, more applicants could be authorized to search for housing at any one time He believes that this approach could simultaneously improve voucher utilization while ensuring a more equitable distribution of vouchers
Housing Voucher Exchange
Households that are supported by vouchers may choose to move In this case, the voucher can travel with them While this fact helps many households every year, it also creates headaches for housing authorities If a household moves from Saint Paul to Minneapolis, for example, Minneapolis is in charge of inspecting the new rental property and paying the landlord, but the money to support the voucher still flows through Saint Paul Therefore, every month Minneapolis must send a bill to Saint Paul In the Twin Cities alone, there are 10 different housing authorities, and these authorities bill each other for thousands of households every month
Arnosti proposes “voucher exchange” as a solution. In cases where Minneapolis is billing Saint Paul for one household, and Saint Paul is billing Minneapolis for another, why not exchange responsibility for these households, and eliminate both bills? Housing authorities occasionally make such exchanges, but they happen intermittently, and only involve two authorities at a time Arnosti believes that the benefits would be much larger if these exchanges were conducted more systematically and involved all of the housing authorities in the region
While exchange could offer immediate administrative relief to housing authorities, it also has potential long-term consequences Paradoxically, Arnosti’s proposal shows that in some cases, conducting frequent voucher exchanges can actually lead to more billing down the line! In other cases, voucher exchange can shift the rate at which different waiting lists move, resulting in more people benefiting from the voucher program Arnosti seeks to identify the circumstances under which these effects occur, in order to ensure that voucher exchange programs do not have unintended consequences.
Other Research Focuses
Shortly after joining the University of Minnesota, Arnosti joined Hennepin County’s Coordinated Entry Leadership
Committee Coordinated Entry is a program that refers people experiencing homelessness to non-profit organizations that offer housing assistance. The Leadership Committee is a group of advisors who offer feedback on the county’s referral policies.
One important question facing the county is, when a spot opens up, which of the many homeless people should receive the referral?
Arnosti is currently working with the county to conduct an analysis of its existing policies Arnosti’s proposal will study policies designed to minimize the size of the homeless population Another crucial consideration in this context is avoiding inadvertent racial bias, but there are not agreed upon definitions of bias or how to measure it Arnosti hopes to collaborate with Hennepin County to tackle this issue proactively
The fourth area of research in the proposal studies policies that seek to reserve housing for specific groups. Arnosti draws inspiration from programs in New York City, where each building has apartments set aside for applicants of different income levels, applicants from the local community, applicants with disabilities, and municipal employees It can be challenging to implement these policies simultaneously, and seemingly minor procedural modifications can have significant consequences Arnosti plans to research policies similar to those in New York City, to better understand their effects
CAREER Grant Goals
Within the five years of the grant, Arnosti has multiple goals One is to have a direct impact on the world By collaborating with partner organizations like counties and housing authorities, Arnosti seeks to help these organizations do more with the limited resources they are given: serving more clients, offering clients greater choice, and ensuring that assistance is distributed equitably Arnosti sees several avenues for immediate collaboration, and anticipates that others will be discovered as the work progresses
A second goal will be to analyze novel theoretical questions inspired by these collaborations. In some cases, this will mean investigating questions which may not directly influence policy, but instead provide foundational work that future researchers could build upon This work will be done in collaboration with ISyE graduate students
“I care about having an impact, but am also excited by the theoretical aspects of the projects Ultimately, I am a mathematician at heart, so I look forward to thinking through new models, doing simulations and data analysis, and solving complex math problems It should be fun!”
OPTIMIZING THE TRANSPLANT SYSTEM
ISyE faculty member Saumya Sinha studies the path of organ allocation and addresses how it serves everyone.
Since her Ph.D. in Applied Math and subsequent postdoctoral work, Saumya Sinha, an Assistant Professor of Industrial and Systems Engineering at the University of Minnesota, has been driven by meaningful, high-impact research Sinha’s work on optimizing the organ transplantation system addresses an important problem: How to design organ allocation systems and policies to improve transplant access?
With regulations always evolving, today’s transplant system is designed to prioritize those who need an organ most urgently. Sinha’s work focuses on optimizing this system.
Most recently, the idea of fairness has entered into her work
“If no transplant hospital is nearby when a deceased donor organ becomes available, that organ is wasted Equally, some areas of the U S do not have any transplant hospitals, so a patient in those areas might not have access to a life-saving transplant ” Studying these scenarios and their outcomes promotes a transplant system that is geographically and socioeconomically equitable.
Although there have been incremental improvements in federal regulations regarding organ transplants, Sinha notes that “ even if regulations remain fixed, their appropriateness will change because the medical field is changing ”
She explains that technological advances, organ transportation, and organ preservation are always improving and evolving Sinha’s work and collaborative efforts with organizations such as M Health, the NSF Engineering Research Center for Advanced Technologies for the Preservation of Biological Systems (ATP-Bio), and the University of Minnesota Institute for Engineering in Medicine are all about informing positive changes in policy that can lead to system-wide benefits
Sinha came to her research focus serendipitously
“I was looking for a postdoc with an applied focus,” she recalls. “I luckily found an opportunity with someone with a long history of research in healthcare and, in particular, organ transplantation.”
This work had her collaborating with physicians trying to understand how federal regulations impacted the behavior of transplant centers, such as hospitals that perform transplants At the time, there were a set of regulations physicians claimed were stifling innovation and hurting patients instead of helping them
“Our work aimed to analyze this mathematically,” she says “Could we find evidence through mathematical modeling and data analytics to support the physicians’ claim?”
Sinha looks forward to continuing to explore the federal regulations of the organ transplant system
“I am interested in exploring how new regulations are better than what was there before what are the shortcomings that persist and could modification or other regulations improve upon these aspects?” she remarks. “I’m also excited to explore the technological improvements in transplant biomedicine Whenever technology evolves, it will affect how the system operates I am broadly interested in how developments in technology interplay with regulations and allocation strategies in the transplant system as a whole ”
With its long history of operations research and systems level analysis, the world of organ transplant drives research that makes a difference
“There is a direct practical benefit,” Sinha reflects, “but at the same time, the inherent complexity of the system makes it fertile for methodological innovation Policymakers recognize the value of the research methods and findings Even a small improvement is an actual life saved.”
GROWTH AND EFFICIENCY IN THE CLOUD
For the past year ISyE Assistant Professor Martín Zubeldía and ISyE Ph D student Yishun Luo have been working together to find ways to improve the operational efficiency of data centers, sometimes also known as the Cloud Originally spurred by Luo, the topic aligns with Zubeldía’s background in Electrical Engineering and Computer Science, as well as his passion for theoretical and algorithmic work.
“Luo was interested in how data centers operate and how to make them more efficient In particular, he was interested in reducing how much computers need to communicate with each other without sacrificing performance With this goal in mind, Luo developed a new load balancing algorithm that has computers communicate much less with each other and still achieve the same performance levels ”
Zubeldía likens their work on improving efficiency of data centers to the progression of the telephone The first telephone network had people manually connecting cables to link different telephones, which was good enough for very small networks This would not work today because of the sheer number of connections that we make every day, so telephone connections had to be made more efficient in order to meet the demands of the users In the same way, the exponential growth in the demand for data center processing capabilities necessitates a similar increase in operational efficiency
“The amount of data and service requests has grown exponentially, and older algorithms aren’t good enough because they don’t scale up appropriately We have to keep up with the level of demand and develop more efficient algorithms in order to meet this growth in demand.”
These efficiency improvements not only appease the user, whether you are streaming, downloading or uploading images and videos, or are a gamer, but it also allows the companies to save money and energy, and invest in their users Initially an ISyE master’s student, Luo’s enthusiasm for learning and his self-driven mentality was what Zubeldía finds most enjoyable about working with Luo Zubeldía is very impressed with Luo coming up with this research direction, and with the new algorithm This shows that Luo has the qualities that will make him an excellent Ph D student Zubeldía is eager to continue his work with Luo and to see him grow as a researcher
Luo explains that the idea for this project emerged almost serendipitously
“As I was experimenting with simulations on various queuing models exploring different approaches just to see what might work a surprising result surfaced. With Professor Martín’s insightful guidance, this discovery evolved into the heart of our research. I am deeply appreciative of my time as a master’s student in our department, which allowed me to take Ph.D. level courses, broadening my understanding of advanced optimization and stochastic models with the guidance of our exceptional professors. Working alongside Professor Martín has been particularly rewarding; he has not only directed my research, but has also demonstrated the qualities of a committed, passionate researcher His dedication to inquiry and mentorship has profoundly influenced my approach to research, and I look forward to learning even more from him as I continue my academic journey Looking ahead, I’m excited to continue making meaningful contributions pursuing research that drives our field forward with creativity and impact ”
For Zubeldía, his research and teaching are all about the theoretical and algorithmic tools that can be used broadly in many application domains He knows that these tools are important for student growth, and can be applied to future projects in the students’ careers
“To learn the tools and be able to apply them anywhere is important. You don’t know where you are going to end up after your Ph.D. - it could be in a finance company, and then at a company like Amazon. All of these companies have different issues, so if you have a good education in the fundamentals, then you can go to any company and make a positive impact The application domain comes from the company, but we should be able to provide the solution ”

ISYE IN MANUFACTURING AUTOMATION
With an undergraduate degree in Mechanical Engineering from North Dakota State University, Sam Boraas began his master’s studies in 2019 and graduated with the M.S. in Industrial and Systems Engineering in the Systems Engineering track in spring 2023. He is now the Director of Mechanical Engineering and Advance Engineering for Critical Handling Solutions (CHS) at PAR Systems
Based in Shoreview, Minnesota, PAR Systems designs and builds custom automated manufacturing systems used in a variety of fields including healthcare, aerospace, and the nuclear industry As the Director of Mechanical Engineering and CHS Advance Engineering, Boraas oversees the mechanical engineering department for advanced manufacturing and critical handling solutions, and oversees engineering support for creating proposals for the design of custom systems
Boraas started working for PAR Systems in 2008 as a contractor and has risen through several positions at PAR since then He saw a chance to advance his career through the University of Minnesota’s Systems Engineering program He was drawn to the possibility of tailoring his coursework to the specific needs of his career path. He was especially interested in broadening his understanding of how to manage software and controls from a systemlevel perspective As his work role at PAR shifted over time, Boraas became more interested in the business side of things The flexibility of the Systems Engineering program allowed him to adjust his coursework to meet that interest Boraas comments that “[the flexibility] was one of the greatest parts of this degree program because it offers people such as myself an opportunity to morph the degree into what works best for them, for their career.”
The curriculum also allowed Boraas to gain a new perspective on aspects of systems engineering For instance, he notes that “(t)he coursework helped me see the process better through our customers’ eyes I got an opportunity to actually develop customer specification documents myself, and I realized how difficult it is and how hard it can be for customers to try to explain what they need when that's maybe never been built before ” Through his coursework, he also expanded his knowledge of accounting, finance, and management
Boraas’ advisor and ISyE Professor William Cooper recalls Boraas’ time in the department and his career now: “It is great to see the interesting things that Sam is working on at PAR For me, one of the most rewarding parts of my job is to see such successful graduates ”
Ultimately, Boraas’ time in ISyE was a fulfilling experience that was immediately applicable and valuable in his career With a strong desire to stay with PAR Systems, Boraas knows that his degree will help him continue to excel in his current position as well as open opportunities for growth in the future

FROM ISYE TO META
As an undergraduate student pursuing a Bachelor of Science in Mathematics, ISyE Ph D student You (Zoe) Zu discovered her passion for optimization and complex problem solving. The rigorous aspects of practical applications led her to the University of Minnesota - Twin Cities to obtain her Master’s of Science degree in Statistics.
The appeal of optimization research led her to join the ISyE department in 2019 as a Ph D student “During my early years of the courses in operations research,” Zu explains, “I was introduced to fundamental concepts of optimization and in supply chain management, which immediately captivated me and my interest deepened when I took my undergraduate thesis, which focused on the bi-level optimization project This advanced area of study involves solving optimization problems that contain other optimization problems as a constraint [ ] it combines a theoretical rigor with practical applications [The ISyE program] has allowed me to apply what I had learned in a meaningful way ”
The ISyE fundamental courses and the course in Game Theory impacted Zu the most because both helped her to understand and further her passion for making optimal decisions The courses also provided a level of rigor and range of learning that greatly appealed to her Equally, the department’s culture and size allowed for opportunities to connect with many other professors and peers who have a wide range of research areas. Zu notes that these connections even stretch beyond her fellow Ph D peers
Not only was she drawn to the culture of the department, but the department’s professors aligned with her research interests - Bayesian Persuasion and Information Design
As Zu explains, Information Design “studies how information can be strategically used to influence decision-making processes, particularly when the sender has more information than the receiver and can control the flow of that information.”
Specifically, Zu’s research is about information sharing in dynamic environments including online platforms and marketplaces, and remarks that the appeal of information design stems from the interest in various applications of the theoretical strategies that she learned and has used throughout her research journey
Zu’s interests in her research seeded from her first project with Associate Professor Krishnamurthy Iyer as a Ph.D. student, which focused on learning to persuade on the fly - robustness against ignorance, and it has
“It introduced me to the fascinating work of information design and how to design the strategies that can effectively influence the decision-making process ”
This initial project led to later collaborations with other ISyE professors and an expert in Information Design in the University of Chicago’s Computer Science department Professor Iyer, who is also Zu’s Ph D Advisor, also remarks on Zu’s journey through her research and the program: “It has been a wonderful experience advising Zoe, and seeing her mature as a researcher over the years She's been extremely productive during her doctoral studies, publishing two conference papers and a journal paper, and having a few manuscripts in submission At the same time, she has been able to get valuable industry experience through various internships. She has thus made perfect use of the time during her PhD as a launchpad for a successful career ahead.”
As Zu nears the completion of her Ph D journey and defends her dissertation in September 2024, she notes the challenge of finding a job in the current job market Thankfully, the program best prepared her for her 2024 summer internship at Microsoft, which has led to full time employment at Meta in Washington state where she will begin as a Research Scientist working on resource management projects on the Monetization Ads Ranking team. Ultimately, Zu looks forward to her new position and using all she has learned while in the department.
been recently accepted by the journal Operations Research
ISyE Ph.D. student You (Zoe) Zu’s studies lead to a position at Meta.
MY ISYE STORY: FELIPE SIMON
I don’t think there is a straight path to a Ph.D. In my case, it probably started during my last year of undergraduate program at Universidad Católica de Chile when I read the book Who Gets What and Why by Al Roth As an Industrial Engineering major, I was taught about how to optimize processes For example, I learned how to manage inventories, analyze queues, route vehicles and every other classic example from an Industrial Engineering curriculum It hadn't occurred to me that markets could be seen as a different form of these problems until I read Roth's book
Roth's work illustrates how various everyday items and services are allocated without the use of money, emphasizing how small rules shape behaviors and outcomes For example, when assigning students to schools, parents are asked to list their preference From a purely Industrial Engineering perspective, if we wanted to maximize the number of students that get their first choice, we could easily write an optimization for this task and call it a day People, being the clever creatures that we are, might realize that if their most preferred school is also highly demanded they might be better off not reporting it in their preference and put a safer choice as their first option By being too optimization-focused we gave parents an incentive to cheat the system (For anyone curious on how people came up with a way to incentivize parents to report their preferences truthfully, I highly recommend exploring Professor Nick Arnosti’s class IE 5285).
Once I realized how these seemingly simple and wellintentioned rules made a substantial impact on how things are allocated, I started noticing them everywhere I wanted to study more of these systems and decided to go to graduate school I applied to the University of Minnesota (UMN) because the Industrial and Systems Engineering (ISyE) department has people that work on the type of problems I am interested in The program seemed very flexible, this would allow me to explore topics that are not often studied in a typical Industrial Engineering program. This convinced me that UMN would be a nice fit for me.
Soon after my arrival in Minnesota I started working with Professor Nick Arnosti After a period of exploration we decided to study how resources are allocated to households experiencing homelessness In particular, we wanted to know how different prioritization rules lead to different levels of unhoused populations We found simple prioritizations that were quite effective I have presented these findings at a couple of conferences, which has allowed great opportunities to meet people with similar interests and to travel around the country
Post-graduation I want to go back home to Chile and find a position in a university so I can continue exploring these problems I am sure that I will find new systems to analyze back home with what I learned at ISyE One problem that has already caught my attention is how cities allocate seats for their free or inexpensive community education classes among neighbors. These classes are always in high demand so having a fair allocation should be a priority. I am excited about teaching these allocation mechanisms because they affect our everyday life, whether we notice them or not.
A PROGRAM OF OPPORTUNITY
Two ISyE Master’s students remark on their time in the program and how it offers a unique opportunity to advance their lives and careers
The department of Industrial and Systems Engineering at the University of Minnesota offers two distinct Master's degrees, M S in Data Science in Operations Research and M S in Industrial and Systems Engineering, Systems Engineering track and Industrial Engineering track Each degree program is carefully crafted to fit student needs and interests, as well as offer an exciting curriculum that positions students for career advancement in a wide variety of industries.
ISyE Master’s students Roman Lidyaev (2025) and Bryan Runyon (2024) discuss their journeys through their coursework and how the program is preparing them for their life and careers after graduation.
Roman Lidyaev
Lidyaev joined the M.S. in Industrial and Systems Engineering, Systems Engineering track in 2023 after receiving his first Master’s degree in Aerospace Engineering.
He ultimately joined the program because of the broad scope and course flexibility including courses taught in various departments within the College of Science and Engineering, and Carlson School of Management
“The broad scope of the program, along with the course offerings and online/classroom options allow for growth and exploration The interdisciplinary approach to the program as filled in the gaps of knowledge I was not exposed to in my previous programs or my career experience This knowledge is invaluable and sets this degree apart from others ”
Along with the knowledge learned from the program, Lidyaev has also seen the value in understanding the higher education system through the Teaching Assistant position for Teaching Assistant Professor Kathryn Wust. Equally, he knows that the program allows him to build his career portfolio, which is an applicable asset for industry needs.
With past and current experience in the Systems Engineering field, Lidyaev notes that the flexibility the department offers is what makes the degree favorable for those in a full time position who desire to return to a degree-seeking program More importantly, however, the faculty within the department create a positive and understanding atmosphere
Lidyaev reflects, “The professors stay on top of the requirements that industries look for, and as a student you feel valued ”
Bryan Runyon
For Runyon, ISyE is the qualitative side of engineering and a discipline that offers the opportunity to see the big picture. His engineering career, however, didn’t begin in ISyE Runyon’s academic journey began with a B S in Mechanical Engineering
The M S in Industrial and Systems Engineering, Systems Engineering track, however, offered multiple opportunities for Runyon
“I always wanted to go to the University of Minnesota - Twin Cities, and the department offered a unique opportunity for me because it seemed to be designed for working people ”
He notes that the program requires no thesis and can be successfully completed with only coursework
The department also allowed Runyon to continue to work while completing his degree in a timely and meaningful manner
“Working and going back to school is such a hard commitment to make But ISyE is flexible, offers diverse electives and required courses, and the professors are understanding of the fact that most of us have full time jobs,” Runyon explains
He remarks that it made the choice to return for a Master’s degree less intimidating.
For Runyon, it is this flexibility that is also an advantage to the degree and its marketability in the workplace.
“Many of my peers are already working in the Industrial and Systems Engineering field, so being able to defend and choose electives that support our interests and current jobs is a huge asset of the program,” says Runyon
Both Runyon and Lidyaev agree that the flexibility of the program is what makes it stand out compared to the rest, and equally both agree that the valuable coursework and the board scope give it a unique and marketing asset
“The degree allows me to work in so many industries,” says Lidyaev
“ISyE is also becoming an in-demand degree, which also makes it worthwhile,” explains Runyon
Ultimately, for Lidyaev and Runyon the M.S. program allows them to further their education and careers. And with the flexible options regarding coursework and learning styles, as well as the approachable departmental community, the program provides all M S students the opportunity to be a part of the robust and growing program
WHAT DEFINES US
I2024 Senior Josh Ichen shares the story of his journey through ISyE and its impact on his future
Class of 2024 senior Josh Ichen enrolled in the University of Minnesota after growing up in a small town in Wisconsin He originally planned to major in Aerospace Engineering and Mechanics, which stemmed from family ties
“My dad’s uncle was an astronaut, so he flew into space when I was a junior or senior in high school. I saw that and thought ‘This is awesome! I want to do this!’”
In the COVID year of 2020, however, he started to look inward at what his career would be like after college, and eventually he made the choice to switch to ISyE Ichen liked the idea that it was a mix between engineering and business, but it wasn’t until his first course called “Foundations of Industrial and Systems Engineering” with ISyE Teaching Associate Professor Darin England that he knew for sure that he was in the right place
Ichen likes ISyE’s focus on making things better He also appreciates his interactions with ISyE faculty members
“The professors are so committed to their students, and students get to know their professors on a personal level,” says Ichen.
He recalls a collaboration with Professor Nick Arnosti after taking the “Engineering the Allocation of Public Resources” course, where he had the opportunity to research a website that served as a community for board gamers Through this
website, people organize "math trades" (trades of used games). Each month, people list games they are willing to trade, and indicate which other games they would be willing to accept in return. Then an algorithm called "trade maximizer" is run to determine who trades with whom Ichen and Arnosti obtained roughly 6 years of trade data, and used it to study how different trading algorithms compared Together Ichen and Arnosti then looked at scenarios where this method would be beneficial to use and compared it to other allocation methods This research project eventually led to a research report, summarizing the findings
Ichen has been able to work on projects that make a direct impact. For example, he applied a shortest path algorithm that he learned in his first ISyE course to Minneapolis crime data to find the shortest and safest path through campus This algorithm could directly impact future University of Minnesota students because, in an entrepreneurship class, Ichen turned his idea into an app that was selected as one of the top five pitches in the class In doing so, he was given the opportunity to work with University of Minnesota students from departments in software development, marketing, and finance to build the app and a website supporting it. The app called SmarterWALK is kneedeep in development. In late November, Ichen and his team will meet with the University Campus Safety Committee to determine the next steps.
His most important and impactful experience during his time in ISyE was the College of Science and Engineering (CSE) Global Seminar: “Design for Life: Water in Tanzania” According to the Global Seminar blog, the program is designed for student teams to make a direct impact on the global community Ichen and his peers evaluated needs and infrastructures of a small Tanzanian community to model a potable waterhandling system. Eventually the model will be evaluated by a local non-profit organization with the funding and resources to take their project to the next level Ultimately, this trip served as an inspiration for Ichen
“I credit a lot of my learnings to this project, which is open to all CSE students ”
In an update Ichen provided in October 2024, “We received full funding for our water project in Tanzania back in May, and just last week they broke ground on building the water system for the village of Makungu.
Fingers crossed the build goes well, and they are expecting to be completed before the winter is over.”
Before Ichen’s graduation, he received two exceptional honors The first was the Dr Alan L Eliason Undergraduate Achievement in ISyE Award This award, which is made possible by a generous gift by College of Science and Engineering graduate Dr Alan Eliason, each year recognizes ten ISyE undergraduate students who have excelled in areas such as leadership, academics, community impact, and innovation For Ichen, however, the meaning of this award goes beyond the scholarship This award reflects his hard work and dedication, and is a true point of pride for him. He was also proud to see nine additional peers who were equally as deserving receive this award.
Ichen was also selected to be the 2024 College of Science and Engineering Graduation Commencement speaker Knowing that graduation is an important moment in the lives of graduates and their families, Ichen took to heart the opportunity and platform to discuss an impactful project and message His speech focused on life after college, encouraging his peers to consider what defines them now and to remind them that grades will no longer be a part of their lives. This idea stemmed from his time in Tanzania.
“I walk through my story of this past year, going to Tanzania and seeing kids just like us, but they don't have access to education or clean water Experiencing that, I wonder how that feels compared to getting raises or making money; what should define us?”
And for Ichen, things that make real impacts in life are what define us all
ISyE Teaching Professor and Director of Undergraduate Studies Lisa Miller could not be more proud of Ichen and all of his accomplishments as she recalls hearing his speech. “I loved hearing Josh encourage his fellow graduates to think about how they will impact the global community ”
In August 2024, Ichen began his career as a Manufacturing Engineer with Boston Scientific in Maple Grove, MN Here he assists in the manufacturing of balloon catheters, which are used to help better patients' lives around the world His studies in ISyE positioned him well for his new job Indeed, he credits
the ISyE program with preparing him for his 2022 summer internship with a startup medical company, which he subsequently leveraged to receive an internship at Boston Scientific in 2023. That internship helped lay the foundation for his new permanent position.
Looking back, Ichen states, “It was cool having a community of students who were connected and I cherish the bond we all had together as students, but that couldn’t have been done without the work of the professors They created the space that we all felt comfortable in ”
Ultimately, Ichen practices what he preaches when he expresses that what defines us all are the impacts we make It is clear that the department of Industrial and Systems Engineering at the University of Minnesota has made an impact on him, but even more so has he made an impact on the department

SENIOR DESIGN PROJECTS
Shop Efficiency and Layout
and Systems Engineering seniors Madelyn Gibbs, Sami Kanukunta, Nicholas Reynolds, Connor Salsbury, and Jacob Voorhees worked with Andersen Windows & Doors for their Senior Design project Andersen Windows & Doors is a private window and door manufacturer headquartered in Bayport, Minnesota.
The team of ISyE seniors worked to improve the operational efficiency of the Andersen Consolidation Center in Menomonie, WI The team focused on improving the picking process, window assembly, and floor layout of the Consolidation Center, with the objective of reducing unnecessary waste and improving product flow within the facility In addition, they sought to decrease processing times and improve worker productivity
The team began by surveying employees to measure satisfaction with the current facility layout and process flow. In this survey the team found that a majority of facility employees had at least 1 suggested change to the facility To dive deeper into the primary challenges in the facility, the team created spaghetti diagrams to map common pathways in the facility used by employees in various roles, and they performed time studies to analyze and identify where inefficiencies occurred The team discovered that workers were making several back-and-forth trips between different locations in the facility to find accessories and put uncompleted projects into storage locations Upon analyzing the congestion, they saw even more significant issues during the corporation’s busy season
(April - October).
Ultimately, to improve the situation and meet the objectives set out by Andersen, the team hosted a Kaizen event, which “ supports an effective, short-term brainstorming session that focuses on a single challenge and improves an existing process ” This event was held with Andersen employees and stakeholders so that al perspectives were represented and any disagreements could be resolved quickly. During the event, the team presented recommendations that included consolidating racks to include various accessories in order to reduce the number of trips, as well as implementing technology to make sorting and allocating accessories easier They also concluded that standardizing barcode placement on products would make for easier access and retrieval Finally, they recommended that organizing the tools in the shop, as well as implementing lift tables and pictures, will ease burdens on employees, improve understanding, and make training more effective.
After the Kaizen event, the team conducted a Paper Doll exercise to mock-up potential redesigned layouts for the shop floor so that product flow could be visualized for different options
In their Final Report, the team concluded that if elements such as barcodes, lighting, organization elements, tablets, and accessibility features were added, the company could have a cost savings of $35,500; 1,372 working hours; and improve shop utilization by 22% per year.
The team reflected on three lessons they took away from their Senior Design Project: clearly outlining project scope prevents wasting; time management ensures tasks are completed effectively; and continuously leveraging each team member’s experience fosters a culture of improvement and increases overall project efficiency
Industrial
Material Flow Optimization
For their Senior Design project, Industrial and Systems Engineering students Valerie Cung, Ash Picione, Kade McTighe, Kara Olander, and Corsten Rylicki partnered with Ergotron to help optimize material flow processes in the company’s Eagan facility Ergotron is a Minnesota-based company that focuses on ergonomic solutions for customer-forward office innovations
The ISyE team saw an opportunity to reduce the time that assembly workers spend on tasks away from the assembly line and to decrease the end-to-end time it takes to produce a product To achieve these goals, the team focused on optimizing two areas of the material flow process: the manufacturing supermarket and outflow from packaging
Ergotron’s manufacturing supermarket is a storage system typically used on an assembly line to store parts that are easily and quickly replenishable To visualize how the flow of the supermarket worked, the team created a flowmap with software platform Miro. The team subsequently suggested that Ergotron employ a Kanban system, which would utilize specialized carts with designated bins to streamline inventory management and the replenishment process In support of this proposal, the team developed an Excel model to determine how many employees are required to maintain the supermarket They also suggested applying the 5S principles (sort, set in order, shine, standardize, and sustain) to create two potential layouts that reduce clutter and optimize material flow
In assessing the state of the outflow from the packaging process, the team created a spaghetti diagram to map and document the existing movement and flows of people and products in the warehouse. The team discovered that there were no set steps for the packaging process, and proposed standard work processes that would result in smoother operations and, consequently, increase productivity and performance
The team also suggested manufacturing automation solutions This suggestion included researching over 50 Autonomous Mobile Robots (AMRs), narrowing their research to 15 AMRs based on technical capabilities
and suitability, and facilitating a decision-making session with Ergotron Ultimately, two AMRs were selected
In their Final Report, the team reflected on three lessons they learned from the project The first was self-guidance, and they state, “Having the freedom to use our knowledge and skills in whatever way we believed would achieve Ergotron’s deliverables let us become much more knowledgeable and confident applying our abilities in a project setting.”
The second was the importance of effective communication On this, they learned that holding regular meetings helped to ensure that the team and Ergotron maintained a common understanding of the project’s scope and goals The third was that projects may bring unexpected challenges “We went into this project anticipating some challenges, but we were still surprised by a few problems that came our way this project further showed that resilience is an important ability of any project team to effectively complete their work.”
