The Department of Internal Medicine is highly committed to the development of academic physicians and physician scientists. As an integral component of this commitment, the Physician Scientist Training Program (PSTP) was created in 2005 with the goal of developing the next generation of University of Michigan academic researchers.
"In 2022, the University of Michigan was awarded $1.72 billion in research funding. Of this, the Department of Internal Medicine was responsible for $269.2 million. In addition, the department published more than 3,946+ research publications."

A Message From Our Director
Thank you for your interest in the University of Michigan Department of Internal Medicine Physician Scientist Training Program (PSTP). We provide our scholars with individualized and comprehensive support and mentorship through every step of their development. They are able to select from a wide variety of research opportunities under the guidance of highly accomplished scientists. Finally, we provide the support necessary for the successful transition of each trainee into an independent research career. In this regard, we make certain that there is support for research training during fellowship, and we also provide incentives that include a minimum of $75,000 of start-up funds and $60,000 in faculty salary bonuses.
Now that our program is over 15 years old, we are excited to report that we have graduated approximately 24 Physician Scientist Program scholars, and of these alumni, 13 individuals have successfully competed for career development awards (i.e. NIH K08 grants or equivalents). In addition, another seven program graduates are in the process of submitting or have submitted career development grants. Of the remaining alumni who decided not to compete for grant support, two-thirds remain in academic positions. Importantly, most of our successful physician scientists remain at the University of Michigan and comprise a rich community that provides peer mentoring to the next cohort of trainees through monthly meetings.
Ultimately, we are very excited about the momentum of our program, and we look forward to recruiting the next group of trainees to join our family.

Training and Environment
Clinical and Research Training
The Department of Internal Medicine is committed to the policies and procedures of the American Board of Internal Medicine’s Research Pathway, assuring that individuals will be eligible for board certification in Internal Medicine and in a subspecialty during the training program.
For the PGY-1 and PGY-2 years, individuals participate fully in the categorical internal medicine program. Because of the shortened period of time spent in the core program, rotation scheduling will be individualized to assure appropriate training before entering the fellowship program.
Close integration is maintained with the University of Michigan Medical School’s Medical Scientist Training Program (MSTP).
The duration of the program will be 6-7 years, depending on the individual’s choice of subspecialty training program. Individuals are eligible for Internal Medicine Board Certification in August of the PGY-4 year, and for Subspecialty Board Certification in November of the PGY-6 or PGY-7 year.
During the final year of the program, faculty appointment as an Instructor is anticipated, based on satisfactory clinical and research progress.
Significant financial support is available for research endeavors and faculty development, based on each individual’s needs and goals.
Individuals enrolled in the program participate in career development seminars during their training, including interaction with MSTP students.
The Department of Internal Medicine provides a vibrant, interactive environment for basic, clinical, and translational research. Michigan Medicine typically ranks in the top 10 for Internal Medicine and in the top 20 for Research and Primary Care per U.S. News & World Report academic rankings.
The Department of Internal Medicine has recruited many physician scientists to join our faculty. Several innovative centers and organized research programs provide an innovative approach to interdisciplinary research.

Laura Felley is an infectious disease fellow starting her fifth year in the PSTP. She got her MD/PhD at the University of Wisconsin, where she spent her graduate school years studying the interaction of invariant natural killer T cells and monocytes and assessing the cellular mechanisms of the inflammatory response that results. She has long been interested in the history of infections and epidemics and knew from the start of medical school that she wanted to be an infectious disease specialist. She has now completed her internal medicine residency and the majority of her infectious disease clinical training at the University of Michigan. She works in Adam Lauring's lab as the resident immunologist, where she studies cellular correlates of influenza immunity in a highly vaccinated cohort.
Steven Grzegorski, MD, PhD studied Biology at Kalamazoo College. He then spent two years working with Dr. Alon Kahana at the University of Michigan studying the basic biology of extraocular muscle regeneration. He entered the MSTP at the University of Michigan and completed his doctoral training in the lab of Dr. Jordan Shavit as part of the Cellular & Molecular Biology.

Jamie Mills, MD, PhD is originally from the Bay Area (Concord, CA) and received her undergraduate degree in Biological Sciences from California State University, Chico. She then matriculated to the MSTP at the Medical University of South Carolina in Charleston, SC. There, she completed her PhD work with Dr. Stephen Ethier on the 8p11-p12 amplicon in breast cancer, demonstrating that amplification and overexpression of genes from this amplicon cooperate to promote overexpression and constitutive activation of the estrogen receptor. This discovery led to her description of a novel mechanism of endocrine therapy resistance in breast cancers. Following completion of her MD, she underwent residency training in Internal Medicine at University of Michigan and is now a Fellow in the Division of Hematology and Oncology in the PSTP at University of Michigan. She has joined the lab of Fil Bednar, MD, PhD, with additional mentorship under the guidance of Dr. Marina Pasca di Magliano to study epigenetics in pancreatic cancer. She plans to pursue a career in GI oncology with focus in pancreaticobiliary tumors and research in epigenetics. View list of publications.

Next, he attended the Case Western Reserve University Medical Scientist Training Program. At CWRU, he was mentored during his PhD by Drs. Peter Scacheri and Jeremy Rich, and his dissertation work focused on transcription regulation in cancer. He found that the non-coding genome shapes extrachromosomal amplifications and their three-dimensional topology to maintain oncogene expression via enhancer elements. He plans to do a fellowship in hematology/oncology.
Jesse Resnick, MD, PhD attended Westminster College in Salt Lake City where he completed a BS in Chemistry with minors in Biology and Physics. He then performed 2 years of pos-baccalaureate research at Los Alamos National Laboratory under the mentorship of Michelle Espy, developing instruments to apply ultra-low field magnetic resonance techniques to functional brain imaging and real-time plant fluid balance monitoring. He joined the Medical Scientist Training program at University of Washington in 2012 where he completed his MD and PhD, through the Neuroscience Graduate Program. His graduate work (under the mentorship of Jay T Rubinstein Md, PhD) leveraged biophysical, computational models of the cochlear implant-brain interface and implantee psychophysics to better understand the fundamental limitations in cochlear implant encoding of fine temporal information. He joined the University of Michigan’s Physician Scientist Training Program in 2012 with an intention to pursue fellowship training in the Division of Pulmonary and Critical Care. His research interest is in developing deeper understanding of pathophysiology through biophysical modeling of biological systems and data science techniques applied to clinical data and imaging.
