Research Experience for Undergraduates (REU) Summer Chemistry Program Our University of Miami, NSF-funded, Research Experiences for Undergraduates (REU) site provides summer research opportunities for undergraduate students from across the United States. The students are offered a choice of research projects encompassing a range of topics related to our theme of the Interface between Chemistry and Biological sciences, which pays particular emphasis on collaborative research.

A central idea is the notion that exciting new avenues of research are being realized when chemical principles are applied to problems in biological sciences. Research-active faculty supervise the students, with each project being a joint effort between at least two faculty members (one each in chemistry and biological sciences). Weekly seminars are conducted to stimulate discussion and provide information on career opportunities, current research issues, professional ethics, and effective communication skills.

At the end Pof the summer, all students participated in our Research Symposium to present their research in both talks HOTO BY MARTIN R. SMITH and posters to the UM community. The participants are also given the opportunity to attend national or regional conferences to further present their summer research and meet with leaders in the field.

New 3-Semester Sequence for Chemistry Majors Beginning Fall 2019, all new chemistry majors (B.A. and B.S.) and minors will take a 3 semester General and Organic Chemistry sequence and their corresponding labs, resulting in a full 16 credits of course and lab work. A highlight of the new courses is that all students will now take part in discussion/recitation sections throughout the semester for each course to reinforce course content in a smaller class size compared to the main lecture.

The previous four semester sequence will be phased out, but will continue for one year to allow for existing chemistry and other science majors to complete their course requirements. The new sequence will provide chemistry majors all of the necessary topics in the discipline to be successful in upper divisional courses. This curriculum transition will allow for students to take new advanced-level courses and electives relevant towards pursing graduate and professional degrees using modern topics in chemistry as the course content. More information can be found in the 2019-2020 UM academic bulletin.

Supporting a Chemistry Trailblazer: The Graduate School’s First Dissertation Fellow

By Laura Elena Lopez Ramos A typical day in the lab for Brian Doherty involves analyzing huge data sets with supercomputers to improve machine learning for quicker and more precise calculations. However, Brian is not a data or computer scientist, Brian is a chemist.

Trailblazing with innovative technologies such as artificial intelligence, Brian studies a relatively unknown branch of chemistry, called computational chemistry, which uses computer simulation, algorithms, statistics, and large databases to analyze chemical reactions. This branch of chemistry allows for more sustainable and eco-friendly lab practices, reducing the need for “trial and error” experimentation, saving lab materials and ingredients, and expediting calculations and results.

Brian, the Graduate School’s first Dissertation Fellow, was one of the first students to study machine learning for computational chemistry at the University in the lab of Dr. Orlando Acevedo, Associate Professor at the Department of Chemistry. His research made strides in improving not only the speed but also the accuracy of chemical calculations by PHOTO BY MARTIN R. SMITH supercomputers. “Calculations that would take a supercomputer six months to complete, now can be done in as little as two weeks,” he explained. “This allows us to explore more accurate chemical information at a faster rate.”

Being at the forefront of this burgeoning field helped Brian land a postdoc at New York University funded by a grant from the U.S. Department of Energy. Immediately after graduating in May, Brian relocated to New York contributing his knowledge in computational chemistry and solvents to NYU’s Tuckerman Research Group to the study of liquid electrolytes inside batteries of renewable energy sources to make them more efficient.

Brian credits the Dissertation Fellowship as one of the main factors that contributed to his academic and professional successes of the past year. The Graduate School’s Dissertation Fellowship, established in 2018, awards $27,225 to one doctoral candidate in their final year of study so they can focus on writing and defending their dissertation without the obligation of a teaching, research, or graduate assignment.

The creation of the Dissertation Fellowship couldn’t have come at a better time for Brian. Towards the end of his fourth year in spring 2018, Brian had become increasingly worried as the NSF grant which provided funding for him as a research assistant had come to an end. Thanks to the Fellowship, he was able to fully dedicate himself to his research instead of relying on funding options like a teaching assistantship.

With his full focus on research, Brian was able to stay on track in the dissertation writing process and finish in a timely manner, as well as dedicate time to related projects which resulted in published work. He has already published four papers, three of them as first author, and he has three more publications pending approval. The most recent of these is a paper on applying a first of its kind machine learning technique to study a unique environmentally friendly solvent system.

To make a gift online, visit: “In general, the Dissertation Fellowship helped me in so many ways. Doctoral students go through so much stress, miami.edu/SupportChemistry especially during the final year when we are writing the dissertation, looking for a job, and, for some, serving as a teaching assistant. Faced with so many competing responsibilities, in many cases I think the research ends up suffering since they do not have enough time to deepen their research or attempt to publish a paper. I am grateful to have had this opportunity,” reflected Brian.

Brian was fortunate to get a head start on the searching job process during the first semester of this final year, securing his dream postdoc in January, months before defending his dissertation. “It was a huge weight off my shoulders. It was better to manage that stress early on instead of at the end when graduation is looming,” he admitted.

Brian Doherty, Ph.D. ’19 was the recipient of the 2018-2019 Dissertation Fellowship.

New Dual B.S./M.S. Degree in Chemistry A new program of study featuring a dual B.S./M.S. degree in Chemistry begins in the Fall of 2019. Students enrolling in the program will earn both a Bachelor of Science (B.S.) and Master of Science (M.S.) degree in Chemistry in a reduced time frame of 5 years. Chemistry’s dual B.S./M.S. degree will improve the academic foundation of undergraduates in the chemical sciences and allow them to become more competitive for employment and/or admission into Ph.D. graduate programs and health professional schools, such as medical and dental programs.

Highly qualified job applicants in the chemical and pharmaceutical manufacturing fields often begin by earning an undergraduate degree and then completing a master’s degree, which generally requires a minimum of 6 years of total training. Students can earn these same academic credentials in 1-2 years less time due to the integrated and focused nature of the B.S./M.S. degree. Students will learn to operate state-of-the-art instrumentation, develop analytical skills, improve their written and oral presentation skills specific to the chemical sciences, and receive the professional training necessary to advance their careers.

Students may do research with any of the graduate Chemistry faculty, in any field of chemistry, including cross-disciplinary studies. The research must be with a faculty member in Chemistry, and does not include sponsored research activities that are centered outside the department, e.g., in the medical school.
