Suren S. Ambegaokar
David O. Robbins Assistant Professor of Neuroscience & Microbiology
B.A., University of California, Berkeley
Ph.D., University of California, Los Angeles
NIH Post-doctoral Fellowship (Neurovirology), University of Pennsylvania
Suren Ambegaokar studies neurodegenerative disorders, infectious diseases of the nervous system, and the intersection of the two. He uses genetic models of human diseases in Drosophila (fruit flies) for use in identifying molecular mechanisms of pathology and to test pharmacological and genetic modifiers of disease.
A native of southern California, Suren Ambegaokar graduated with a B.A. from UC Berkeley with a double-major in Molecular & Cell Biology (Neurobiology) and Film Studies. After college, he worked as a research associate in the lab of Greg Cole at UCLA studying molecular mechanisms of Alzheimer disease in transgenic mouse models and human brain tissue. He later enrolled in the Neuroscience Ph.D. program at UCLA under the mentorship of George Jackson. His dissertation work focused on human genetics and Drosophila models of neurodegeneration, specifically as related to the protein, Tau. Dr. Ambegaokar continued this research as a post-doctoral fellow after Dr. Jackson was recruited as the director of the Mitchell Center for Neurodegenerative Diseases at the University of Texas Medical Branch (UTMB) in Galveston, TX. As studies into inflammation and immunology in the brain were providing many needed insights into neurodegenerative diseases, Dr. Ambegaokar studied HIV infection in the brain under a NIH postdoctoral fellowship at the University of Pennsylvania in Philadelphia, PA, under the mentorship of Dennis Kolson. In 2014, Dr. Ambegaokar started as an assistant professor of Neuroscience and Microbiology at Ohio Wesleyan University, serving in both the Department of Botany and Microbiology and the David O. Robbins Program in Neuroscience.
Professor Ambegaokar loves to travel, and you can stop by his office to borrow travel books on Chile, Scotland, India, Pakistan, China, and Guatemala (among others), or stop by for any other discussions on classic and foreign films. He lives with his wife and their 4 amazing cats in Lewis Center, OH.
