Physiology of Color Vision
Jacob Baudin completed his dissertation research under the mentorship of HHMI Investigator, Dr. Fred Rieke, in the Department of Physiology and Biophysics. Jacob studied the neuroscience of color vision. Employing a multidisciplinary experimental and computational approach, Jacob discovered unexpected heterogeneity among distinct cone cell types in the primate retina, extending throughout all levels of spatial, spectral, and neurocortical organization. Jacob has additionally distinguished himself due to an enduring interest in computational science. Concurrent with, yet independently from, his PhD research, Jacob worked with Dr. Shwetak Patel, a Professor in the UW School of Computer Science & Engineering, to apply machine learning to develop a smartphone app to measure pupillary light responses, for traumatic brain injury diagnosis. This passion led him to perform a summer internship culminating in a one-year position as a software engineer at Google headquarters in Mountain View, California, in-between the conclusion of his dissertation research and before re-entering clerkships. At Google, Jacob developed medical diagnostic machine learning algorithms. While performing clerkships, Jacob has collaborated with MSTP alumnus and surgical resident, Dr. Katie Liu, to create a smartphone game controlled by skin electrodes recording muscle activity, in order to speed recovery from nerve injuries. The UW MSTP has a long history of MSTP students performing computational internships. In fact, UW MSTP alum, Bud Tribble, led development of the Apple Macintosh operating system while a student in our program; Dr. Tribble is a legendary senior executive at Apple and continues to develop health enabling technologies, such as the EKG features of the Apple Watch.

Translational Control in Cancer
Elise Cai performed her dissertation research in the Molecular and Cellular Biology Program under the mentorship of Dr. Slobodan Beronja at the Fred Hutchinson Cancer Research Center. Elise addressed the clinically and scientifically important question of why the skin lesions in individuals with neurofibromatosis and other inherited disorders of RAS signaling tolerate a surprisingly high burden of oncogenic mutations and thereby resist malignant transformation. She discovered a new protein translational mechanism regulating production of a key ubiquitin ligase, involved in protein degradation. In collaboration with Dr. Andrew Hsieh’s lab at the Hutch, she discovered similar translational regulatory pathways involved in prostate cancer. During clerkships, Elise has helped organize a project delivering home health care during the COVID-19 outbreak.

Genome Instability During Aging
Ken Chen performed his dissertation research in the Department of Genome Sciences under the mentorship of Dr. Matt Kaeberlein, one of the world’s leading authorities on the biology of aging. Ken’s project was multidisciplinary, encompassing both bioengineering and genetics. He studied yeast, an established model organism for investigating aging, and engineered a microfluidic device to capture aged yeast cells. He discovered that as yeast age, they become deficient in iron prosthetic groups needed for aerobic metabolism and DNA replication fidelity. His were the first studies to implicate iron metabolism in aging. Interestingly, since then, human genome-wide association studies have similarly identified iron metabolism as a significant genetic pathway contributing to human aging.

Cardiac Regeneration
Miles Freeman is a student in the Morehouse School of Medicine/University of Washington MSTP pathway. He earned his PhD in the Molecular and Cellular Biology interdisciplinary program in the laboratory of Dr. Robb MacLellan in the Division of Cardiology in the Department of Medicine at the University of Washington. The goal of Dr. Freeman’s research is to promote cardiac regeneration in patients after suffering a myocardial infarction. He has pursued a new strategy of coaxing otherwise terminally differentiated cardiac myocytes to re-enter the cell cycle. An epigenetic mechanism limiting cardiac myocyte cycling in adult cardiac myocytes involves trimethylation of lysine-9 of Histone H3 (H3K9me3), a modification associated with repressed chromatin, which silences expression of cell cycle genes and ordinarily restricts heart regeneration following injury. He found that KDM4D, a demethylase targeting H3K9me3, can reactivate cell cycle gene expression and mitigate cardiac myocyte damage in response to ischemic injury. He is currently completing the clinical phase of medical school at Morehouse School of Medicine in Atlanta.
