LETTER FROM THE
DEPARTMENT HEAD Underserved Populations Engineering Research Center (NSF ERC). These programs support academic research aimed at translational efforts to quickly move design concepts developed in our labs out into practice, where patients are in need. It is a thrill to work with faculty and students so committed to solving problems that are not considered “big enough” or “profitable” for industry to address with commercial products.
Dear colleagues and supporters, I am excited to share the 2019 annual update for the Department of Biomedical Engineering at Texas A&M University. Our entire team of faculty, students and staff have a fundamental commitment to making an impact. Dedication to this desire not only influences our strategy on hiring new faculty and developing training programs for students, but it affects our daily activities in the lab, in the classroom, and in the clinic and field. I am pleased to highlight some exciting research developments, celebrate the achievements of our faculty and students, underscore the impact of their innovative and translational research, and recognize their elevated status in several professional societies. As we move into the future, we will be maintaining technical emphasis on our four primary research areas of Imaging Technologies, Medical Devices, Regenerative Medicine and Sensing and Monitoring Systems. At the same time, our faculty is expanding to bring complementary expertise in application areas of great importance throughout the world: chronic diseases (cardiovascular disease, cancer, diabetes), trauma care and pediatric devices. We expect this will enhance our ability to impact these critical areas, which are already strongly supported with two of our federallyfunded research centers — the SouthWest National Pediatric Device Innovation Consortium (FDA) and the Precise Advanced Technologies and Health Systems for

Students are choosing Texas A&M for graduate studies because they want to work with faculty and other students that maintain a similar focus on translation. The opportunities to work with clinical and/or industry partners that are similarly committed to turning concepts into products while pursuing their degrees are also very appealing. In turn, we are engaging closely with these external partners and constantly evolving our graduate programs to ensure that our students are well-poised to quickly meet the needs of industry and innovative clinicians. We expect these students to be impact-minded leaders that will not only design engineering solutions to clinical problems, but understand all aspects of the process necessary to turn those into approved products — that is the only way to truly advance health care for the future. It is through this comprehensive training, delivered by distinguished leaders in the field, that we have confidence in producing complete biomedical engineers, prepared to have a lasting influence on our state, our nation and our world. This strategic focus is paying off, as evidenced by the increase in research expenditures, publications, faculty awards, graduate student fellowships and research space. These achievements are enabling further growth in faculty and student numbers that will provide even greater opportunities for impact. Please visit our website engineering.tamu.edu/biomedical or come visit us in person to see firsthand how our plans are coming together to make a difference in the world.

HAGLER FELLOWS CONTRIBUTE TO RESEARCH, EDUCATION The department has the unique opportunity of collaborating with two esteemed faculty members from outside universities through the Hagler Institute for Advanced Study at Texas A&M University.
to rather unique clinical facilities in Brazil, which can be potentially used by our faculty members. I am planning to visit those next month and look forward to future collaborations.”
Dr. Vanderlei Bagnato is a full professor in the Department of Physics and Materials Science at the University of São Paulo and the Institute of Physics of São Carlos, Brazil. Dr. Maryellen Giger is the college vice-chair for basic science research in the Department of Radiology at the University of Chicago. Both have found ways to impact students and faculty at Texas A&M.
This fall Giger is co-teaching “Special Topics in Computer Vision and Machine Learning in Biomedical Imaging.” The course teaches students basic concepts in computerized image analysis and machine learning in biomedical imaging, image processing, feature extraction, feature selection methods, radiomics, deep learning, and evaluation methods using current figures of merit and statistical techniques.
Bagnato has visited campus to speak and visit with faculty and students in the department about their research, as well as give several guest lectures. He is working on two research grant proposals with Dr. Vladislav Yakovlev, professor in the department, and plans are underway to set up a joint experiment with the Health Science Center, for experiments with participation of biomedical engineering students. “He brings a rather unique combination of expertise in fundamental science (quantum physics) and translational biomedical optics (photodynamic therapy and photobiostimulation),” Yakovlev said. “He has access
“It’s not a programming course; it’s a course to see the big picture of biomedical image analysis and understand where images come from and why they are taken,” Giger said. “The goal is to enrich students more in image analysis. A system is both acquisition and interpretation of images. The department is great on the front part, but my expertise is on analysis.” Bagnato and Giger have each visited Texas A&M several times and regularly communicate with faculty on topics ranging from research discussions to grant proposal collaborations.

PETTIGREW LEADS INNOVATIVE PROGRAM TO COMBINE MEDICINE AND ENGINEERING Dr. Roderic I. Pettigrew has only been at Texas A&M University for about two years, but he has already spearheaded some impactful programs, including Engineering Medicine (EnMed), a new initiative to bring forth a new kind of converged physician and engineer, a physicianeer. “The driver for EnMed is the desire to be as impactful and transformative as we can in addressing complex medical problems,” Pettigrew said. Pettigrew serves as executive dean of the EnMed program, which was created through a three-way partnership between the College of Engineering, College of Medicine and Houston Methodist Hospital. EnMed is the nation’s first four-year, fully-integrated engineering and medical education curriculum leading to both a doctor of medicine degree and a master’s degree in engineering. “Students are required to invent something that addresses a health care challenge or problem,” Pettigrew
said. “To do that, both research and its translational are required. What good is an invention if it doesn’t help solve a problem or can be used to advance our understanding?” EnMed is an subsidiary of the EnHealth program at Texas A&M, where Pettigrew serves as chief executive officer. He also holds the endowed Robert A. Welch Chair and is a professor in the Department of Biomedical Engineering. The inaugural class has recently begun, and Pettigrew said he looks forward to seeing what kind of minds the program creates, minds he says we have not encountered yet. “I was a physicist, then an engineer, then got my Ph.D. in applied radiation physics, and then I went to medical school. But I didn’t learn the quantitative and life science fields in a blended fashion,” Pettigrew said. “The great hope is that we will create this new kind of bilingual mind poised to make a transformative difference in the health care world, full of problem solving physicians, great imagineers, great innovators and inventors.” While EnHealth and EnMed have been Pettigrew’s primary focus for the last few years, he looks forward to jumping back into the research arena soon. He is forming multiple collaborations within the cardiovascular area and has received a Governor’s University Research Initiative grant and an endowment from the Welch Foundation. His goal — to end heart attacks. “We don’t have to have heart attacks,” Pettigrew said. “There’s nothing in nature that says humans must have heart attacks. It’s not a requirement of life.” Pettigrew served as founding director for the National Institute of Biomedical Imaging and Bioengineering at the National Institutes of Health. Prior to his appointment there, he was on the faculty at Emory University School of Medicine as a professor of radiology and medicine (cardiology), and at Georgia Institute of Technology as a professor of bioengineering. He is an elected member of the National Academy of Medicine, the National Academy of Engineering, the National Academy of Inventors and is an elected foreign member of the National Academy of Science, India.

Research Highlight: Regenerative Medicine “My research is on hydrogel biomaterials, which can be used to deliver cells and other therapeutics and promote tissue regeneration. Our research spans from fundamental studies on hydrogel chemistry and biological responses hydrogels to applicationspecific studies on the efficacy of hydrogels we design. With continued investment in regenerative medicine research, I expect we will achieve unprecedented capabilities in repairing the human body from injury and disease in the near future. Humans are largely incapable of tissue regeneration, and degenerative diseases take a significant toll on the health and wellbeing of millions of people. Solving these problems would have an enormous impact.”
Dr. Daniel Alge “We’re working with extracellular matrices, tissue made by stem cells that mimics the composition of regenerating bone tissue. This accelerates bone healing. Instead of gathering the tissue from patients, we’re growing the tissue in a dish. We then harvest this and combine it with engineered scaffold using microfluidic techniques to make it more effective for bone regeneration surgery. This is a new paradigm for how to make tissue. The goal is to make this material and stem cells in general in a scalable way that is manufacturable. Right now, the technology exists, but methods of making it efficiently in large quantities still needs to be worked out. This is being addressed as part of a multidisciplinary grant involving the College of Medicine and our department.”

Regenerative medicine research in biomedical engineering seeks to create living tissues to replace tissues or organs lost due to age, disease, injury or congenital defects. Our faculty are pursuing innovations in biomaterial platforms include “smart” materials, biomimetic nanomaterials, functionalized hydrogels and therapeutic delivery systems. We asked our faculty what projects they’re currently working on and what impact they think regenerative medicine has in the health care field.
We are excited to add two new faculty to the group this year. Read more on pages 28-29. · Dr. Isaac Adjei, assistant professor · Dr. Shreya Raghavan, assistant professor
“Our research is focused on developing tissue engineering scaffolds that can enable healing of orthopedic tissues. To treat irregularly shaped craniomaxillofacial bone defects, we are developing “self-fitting” scaffolds that conform to the defect space, which is necessary for healing. To treat osteochondral defects of the knee, we are preparing implants comprised of a hybrid hydrogel scaffold that stimulates bone formation and a synthetic cartilage cap for resurfacing.”
Dr. Melissa Grunlan
“Our research has contributed to the fundamental design and application of twodimensional nanomaterials — important for the development of smart and responsive biomaterials for regenerative medicine and therapeutic delivery. Specifically, we have developed multiple technologies to facilitate repair and regeneration of damaged tissue ranging from bioactive nanomaterials for bone regeneration and augmentation, bioactive materials for osteoarthritis treatment and injectable bandages for traumatic injuries.”

“My team and I have developed biodegradable shape memory polymer foam. The first applications of the material is to occlude blood vessels for indications like dissected aortas and neurovascular aneurysms. The key features of the implanted materials is that they form clots rapidly and only where doctors want the occlusion, recruit a healing response to the implant site and bioresorb after their function is served. So far, 20 years of work have resulted in two devices approved for use in the USA and Europe. We are currently researching new uses for the materials in hemostatic and cancer applications.”
Dr. Duncan Maitland
“Significant technical (design and manufacturing), preclinical testing, clinical and regulatory testing challenges exist in the field of pediatric devices. Clearly a different model of product development and clinical translation is needed for pediatric device innovation, one that is based on nonprofit motives and a fundamental passion to improve, and in many cases, save lives of pediatric patients.”
Dr. Balakrishna Haridas
“For people who go into biomedical engineering, it’s about impacting patients, so how do you improve patients’ lives through either therapeutic or device products. The goal of helping patients and the goal of innovating medical devices go hand in hand. I don’t think you can separate those.”

With a strong translational emphasis, research in medical devices focuses on technological advances toward and supporting product design and development. Primary topics include on-chip systems that mimic vascular physiology to assess blood disorders, interventional tools for treatment of stroke and aneurysms, and devices to support heart healing after infarction Our faculty took some time to summarize their current research and discuss how medical device research impacts the health care field.
Dr. Reza Avazmohammadi will be joining the faculty this year as a new assistant professor, bringing expertise that will support the medical devices group as well as regenerative medicine. Read more on page 29.
“I’ve been in the world of startup companies for almost 15 years and have launched multiple startup companies. I have practice pitching to investors and teaching others how. The whole idea of professors of practice was to share this learning, how you take a medical device from its earliest conception and take through all the stages, which involve basic concept, design, lab testing through FDA to market and sharing with them how it’s done. It’s fun. I’m helping teach innovation entrepreneurship. When we are teaching we are using examples from our careers in the classroom. Teaching with real-world experience helps concepts make more sense, which is a big benefit.”
Dr. Saurabh Biswas
“My research focuses on how mechanics – the study of force and motion in matter – applies to the biology of the heart and how to utilize such knowledge to obtain better clinical outcomes. Toward this end, we invest, design, prototype and test devices that correct the mechanical performance of the heart in order to improve heart repair and function.”
Dr. John Criscione
“Our team works at the intersection of two large fields of bioengineering, one is tissue engineering, and one is biomicrofluidics. When you merge the two, a new field is born which we call organs-on-a-chip. This discipline of bioengineering aims to act as an alternative to current test models, provides potential to advance personalized medicine because it offers the flexibility to make patient specific organs-on-a-chip and allows us to model complex physiology using bioengineering at a very high resolution.”

“I think there are few things that are more compelling than trying to improve human health. I’ve always looked at that as something that draws me, something I feel that if I can help out, that would be a really impactful experience,” said graduate student Tokunbo “T.J.” Falohun. “Biomedical engineering boils down to using technology to improve human health.” Falohun joined the department in 2017 to pursue his master’s degree. He said three reasons drove his decision to come to College Station: the large variety of research taking place within the biomedical engineering department, the translational emphasis on the research that occurs within the department and the numerous opportunities available to students. Falohun works in the Biosensing Systems and Materials Lab under the direction of department head Dr. Mike McShane, helping to develop small-molecule biosensors — miniature analytical devices used to measure biochemicals in the body and cell/tissue samples for medical research and clinical application. One example of the research performed at the lab is the measurement of blood sugar levels for individuals with diabetes. A biosensor, which is implanted under the skin, can respond to blood sugar levels for extended periods

without the need for finger pricks. The implant can then be “read” using an external device to inform a patient on their current condition, giving them more control of their health. “The field of biosensors, I think, is one of our most compelling subdisciplines within biomedical engineering because it enables people to better maintain their conditions,” Falohun said. “It saves tons of money as opposed to going to the doctor to get tests. If we can monitor our own health, you can prevent a lot of these chronic diseases that develop.” So far, the team has developed a biosensing platform to measure oxygen, glucose and lactate. For his master’s thesis, Falohun worked to expand the list to include uric acid, a substance that, when it crystalizes and deposits in joints, can cause gout. Falohun transitioned to pursuing his doctoral degree in the summer of 2019. His end goal is to contribute to the development of life-saving medical technologies. Falohun has disseminated the result of his research on sensors for managing gout at various professional meetings, including the National Society of Black Engineers’ annual convention and the Biomedical Engineering Society’s annual meeting.
TEXAS A&M ENGINEERING | engineering.tamu.edu
FALOHUN HAS A SENSE FOR COMPELLING RESEARCH He has also taken his research to the next level by participating in entrepreneurial ventures while on campus. He entered the Raymond Ideas Challenge, hosted by the McFerrin Center for Entrepreneurship. His idea was a user-friendly approach to diabetes management using biosensors and connected electronics.
Innovation Corps (i-Corps) program to explore the commercialization potential of implantable biosensors.
The idea was inspired by work in his lab, where the team develops implantable hydrogel biosensors for chronic disease management. Falohun said his experience in the Raymond Ideas Challenge would have been impossible without the supportive environment provided by McShane, his research group and the biomedical engineering department.
The GRFP provides three years of financial support within a five-year fellowship period — a $34,000 annual stipend and $12,000 cost-of-education allowance to the graduate institution.
“Entrepreneurship really excites me,” Falohun said. “In my view, the prospect of turning an idea that previously didn’t exist into a product or service that can improve the lives of people is a challenge worth undertaking.” His other recognitions and activities include receiving the 2018-19 Outstanding Engineering M.S. Graduate Student Award, tutoring K-12 students from underserved communities in math and reading comprehension, mentoring young people to pursue higher education in the STEM fields, leadership council member for 3-Day Startup and participation in the National Science Foundation
Falohun’s impact in the department has not gone unnoticed. He was awarded a National Science Foundation Graduate Research Fellowship Program (GRFP) grant in 2018.
“I am incredibly honored to receive this award and am very proud to represent the Department of Biomedical Engineering, as it has provided me with opportunities that have been essential to my growth as a graduate student,” Falohun said. This year, four students in the department received the GRFP: Annie Hedman, Shannon Ingram, Mark Keppler and Jim Tronolone. The NSF Graduate Research Fellowship Program recognizes and supports outstanding graduate students in NSFsupported science, technology, engineering and mathematics disciplines who are pursuing research-based master’s and doctoral degrees at accredited United States institutions.

TAKING ON PEDIATRIC CARE CHALLENGES
To help younger patients, researchers at Texas A&M University are working with Texas Children’s Hospital and a group of clinical and commercial partners to develop pediatric medical devices. The SouthWest National Pediatric Device Innovation Consortium hospital and university partners work to identify unmet pediatric device needs, and design and test pediatric device prototypes that can be developed into viable pediatric medical devices.
Contextual Inquiry Projects This project aims to apply the contextual inquiry process to two clinical areas to discover unmet needs and potential engineering problems to tackle. The photo (Left: Victoria Baldock; Right: William Stewart) shows the needs discovery process applied to the Type I Diabetes space where the team maps out Points of Pain and Points of Delight expressed by stakeholders to find common themes that emerge. Collaborator: Texas Children’s Hospital
Bio-Synthetic Tracheal Graft Project This project aims to develop a bio-synthetic tracheal graft for use in tracheal reconstruction in children with Congenital Tracheal Stenosis (CTS), a rare birth defect where current treatment methodologies are lacking. The new graft will allow for tracheal remodeling and also provide mechanical support during the remodeling process. The photo shows a trachea reconstructed with the device in a test bench designed to expose the trachea to cyclic pressure changes while measuring pressurevolume relationships. Collaborator: Cincinnati Children’s Hospital 18
TEXAS A&M ENGINEERING | engineering.tamu.edu
At Texas A&M, a team of engineers and graduate students is working on a substantial portfolio of pediatric devices that include the development of a biosynthetic growth accommodating tracheal graft, new minimally invasive methods and instruments for fetal surgery, synthetic urinary sphincter valves, wireless urinary bladder sensors, devices and software for remote monitoring of Type 1 Diabetes patients, and numerous other upcoming applications in pediatric interventions. Several of these examples are featured below. Devices and surgical technologies for pediatric patients are technically challenging to develop, which increases the cost of development as well as the time frame for successful implementation of complex technological solutions with safety and efficacy as the primary goals. Learn more at swpdc.org.
Synthetic Urinary Valve This project aims to develop a synthetic urinary valve for use in patients with neurogenic bladder. This condition results from spinal cord afflictions such as spina bifida and leaves the patient without bladder control. The valve aims to prevent urine leakage, allow for catheterization for manual voiding and prevent over-pressurization of the bladder. Given the prevalence of infection in urinary tract devices, anti-microbial properties are important to the success of this device. We’re incorporating polyethylene glycol additives developed by Dr. Melissa Grunlan’s group at Texas A&M into the silicone to provide anti-microbial and anti-fouling properties to the synthetic urinary valve. The photo shows a prototype valve deployed in a female bladder model. Collaborators: Texas Children’s Hospital and Baylor College of Medicine
Chorioamniotic Membrane Anchor Conditions such as spina bifida can be corrected through fetal surgery which leads to significantly improved outcomes for both mother and child. Fetal surgery, when performed fetoscopically, frequently results in separation of the chorioamniotic membranes post-surgery which leads to premature birth. Currently, the uterus is exteriorized at the time of surgery to place stitches that anchor the membranes to the uterine wall. We’re developing a device to anchor the membranes in a fully percutaneous procedure that is significantly less traumatic to the mother. The photo (Left to Right: Dr. Balakrishna Haridas, Achu Byju, Madison Hughes) shows the anchor system in its intended location. Collaborators: Texas Children’s Hospital and Baylor College of Medicine

NATIONAL EXCELLENCE FELLOWS PROGRAM BRINGING THE BRIGHTEST TO AGGIELAND The doctoral program landscape across the country is increasingly competitive, with top candidates receiving multi-year high-salary offers, signing bonuses and travel funds from multiple highly ranked programs. The National Excellence Fellows Program (NEFP) was created within the department to help attract these high-achieving students. Jim Tronolone is a first year Ph.D. student in Dr. Abhishek Jain’s lab working on organ-on-a-chip devices, specifically researching type 1 diabetes treatment. Tronolone said he is interested in working to vascularize islets (help the formation of new blood vessels), which can be transplanted as a diabetes treatment. “The motivation is to improve islet survival following implantation. Currently, islet replacement therapy has low success because the islets die before new vasculature transporting oxygen and nutrients can form,” Tronolone said. “My project involves trying to vascularize islets on
a chip and analyze their exocrine functions, and we’ll eventually move on to adapting the model so that we can 3D print implantable grafts.” Tronolone was finishing his master’s at George Washington University when Jain’s name came up in class. Jain had reached out to a colleague looking for prospective Ph.D. students. Tronolone had come across Jain’s name before. “I’ve been doing organ-on-a-chip research since last year. My previous lab was another organ-on-a-chip lab and just from doing work there I stumbled upon his research,” Tronolone said. The NEFP is designed for students pursuing their Ph.D. in biomedical engineering, specifically those intending to pursue translational research that impacts the biomedical engineering industry.
Eligibility Requirements • Apply to the Ph.D. program in biomedical engineering via EngineeringCAS and submit all supporting documents no later than December 1. • U.S. Resident • Received or will receive a B.S. degree in an engineering degree from an accredited U.S. institution prior to starting the Ph.D. program • Recommended GRE scores of 164-Q/156-V or higher • Recommended GPA of 3.75 or higher • Minimum of two years of research experience

Jain, assistant professor, said through the NEFP, faculty have additional incentive to actively recruit prospective students who would otherwise be going to the top five schools in the country.
to also apply for external fellowships. Tronolone was recently announced as a recipient of the National Science Foundation’s (NSF) Graduate Research Fellowship Program (GRFP).
“It encourages faculty members to get engaged with some of these brightest students and advocate their work,” Jain said. “[Jim and I] were constantly in touch and he was very well aware of the work that we do. He was very excited to be a part of our lab and I was very excited to have him.” Participants receive a $38,000 annual stipend, a $17,000 cost-of-education allowance, an invitation to special networking opportunities with industry and academic partners, and the opportunity to complete internships with industry or national labs, or complete training programs on related careers in academia.
“The National Excellence Fellows Program was developed with the intention to attract top graduate student prospects — those with extensive research experience and outstanding potential as leaders — with a rare opportunity to focus on translational work,” said Dr. Michael McShane, department head and originator of the NEFP concept. “This is a very different emphasis than traditional fellowship programs (NSF, Hertz, etc.) and is more aligned with our departmental goals. Still, we have had students win both NEFP and NSF GRFP awards — they are just so impressively prepared that they are able to bridge the fundamental and applied research.”
Another goal of the program is for faculty and students to work together to help the student leverage the NEFP
The department expects to offer two-three NEFP awards per year.

RESEARCH SERVING THE UNDERSERVED GETS A NEW HOME A major engineering research center led by biomedical engineering faculty now has a new home on campus. In 2017, the National Science Foundation (NSF) awarded a $25 million grant to Texas A&M University and its partners to pursue low-cost technology for diagnosing and monitoring markers of diabetes and cardiovascular disease. This led to the formation of the Precise Advanced Technologies and Health Systems for Underserved Populations (PATHS-UP) Engineering Research Center (ERC), which moved into its new home in the Health Technologies and Innovation Building in February 2019. The 25,000-square-foot facility houses over 10,000 square feet of dedicated laboratory space that includes a shared Biosafety Level 2 lab, a Class 10,000 clean room, a chemistry lab and several faculty research labs. The facility also houses 13 offices, five bullpens (student rooms) and two conference rooms. The goals of the PATHS-UP NSF-ERC is to engineer transformative, robust and affordable technologies and systems to improve health care access, enhance the quality of service and life, and reduce the cost of
24
health care in underserved populations. It also aims to recruit and educate a diverse group of scientists and engineers who are ready to lead the future in developing enabling technologies to improve health in underserved communities. The team is led by researchers at Texas A&M, with partners from the University of California at Los Angeles, Florida International University and Rice University, and includes assessment experts from the University of Illinois at Urbana-Champaign. “The PATHS-UP multidisciplinary team is excited to be in a space with the INVENT team that fosters an atmosphere for creativity, collaboration and exciting research,” said Dr. Gerard Coté, director of the Center for Remote Health Technologies and Systems. Coté, who is holder of the James J. Cain Professorship I in the Department of Biomedical Engineering, said the building will be a place to collaborate to facilitate the center’s goals to engineer transformative, cost-effective medical technologies that can be used in underserved communities.

“Specifically, it provides the space to accomplish the research thrusts of PATHS-UP, including such research as the development of nanoparticles, assays, paper fluidics, readers, wearable devices with flexible electronics and the data analytics,” Coté said. Beyond the research pillar, PATHS-UP includes the pillars of culture of inclusion, innovation ecosystem and workforce development, including college and precollege programs. The new space will facilitate annual workshops, house STEM post-docs, graduate students and undergraduate students doing research, industry representatives from top medical device companies, and K-12 teachers and students. These pillars are supported by internal programs such as the Research Experience for Undergrads and Summer Research Experiences for Teachers and Young Scholars. PATHS-UP is a part of the Center for Remote Health Technologies and Systems, where researchers are developing breakthrough remote health technologies, algorithms and health analytics as well as using advanced systems engineering to solve the global health grand challenges and enable healthy living.

ANNUAL RESEARCH SYMPOSIUM PROMOTES A CULTURE OF EXCELLENCE Even before the first day of the fall semester, graduate students in the department are put to the test during the Annual Research Symposium. This is the third year for the event, which was started to display and promote the culture of excellence in the department. Students present on their work, allowing other students to learn about cutting-edge research
26
happening in the department and become familiar with technical presentation skills. The symposium encourages and fosters future collaborations both within and outside of the department. Dr. Michael McShane, department head, said it also allows all students, including incoming graduate students, to interact and network with senior and peer researchers.
TEXAS A&M ENGINEERING | engineering.tamu.edu
“Our commitment here is not just to do excellent research, write a lot of papers and graduate students that are able to contribute in industry and in academic circles. We also need to have our research make an impact in the future, meaning it gets to the hands of people who are going to apply it in the clinic, in the home, to make a difference and improve their quality of life,” McShane said. The symposium is organized and run by a committee of graduate students who work to plan the agenda, help students find their way and connect with event sponsors. “It was a great opportunity for me to learn and shape my event management and planning skills,” said Sakina Mohammed Mota, doctoral student and this year’s committee chair. “I will always be thankful for being given this chance. It was a very rewarding journey.” The symposium has evolved over its three years of operation. This year’s event introduced rapid-fire
presentations, invited speakers during lunch and undergraduate research presentations on top of the established graduate oral and poster presentations. “Perhaps one of the best experiences was receiving questions from the incoming students. Their ability to review our work with fresh minds and outside knowledge produces insightful questions that serve to improve and strengthen our research,” said Lance Graul, doctoral student and last year’s symposium committee chair. Plans to continue growth are already in consideration, and the students are looking into ways to include medical research groups as well as other external academic departments at Texas A&M — particularly those with whom faculty have extensive collaborations — to gain additional expert feedback on research projects and further foster partnerships.
