Biography

Dr. David RaskinDavid Raskin, Ph.D joined the Marian University College of Osteopathic Medicine in 2013, and currently is an Associate Professor of Microbiology. Dr. Raskin teaches topics in bacterial infectious disease throughout the first two years of the integrated curriculum. Dr. Raskin earned a B.S. in Biology from The Ohio State University and an M.S at the University of Dayton. He received a Ph.D. from Case Western Reserve University in the Department of Molecular Biology & Microbiology, studying cell division in Escherichia coli. As a post-doctoral fellow at Harvard Medical School, he began studying Vibrio cholerae, the causative agent of the epidemic diarrheal disease cholera.

Dr. Raskin currently studies how V. cholerae respond to environmental changes and how it uses that information to regulate virulence gene expression. As the organism moves from the environment to a human host, it has to respond to changes in the local environment, and these responses include the production of virulence factors that cause disease symptoms in humans. In addition to his teaching and research, he has served as an NBOME item writer and reviewer, and is an ad hoc reviewer for many journals.

Dr. Raskin enjoys traveling and spending time with his wife exploring the food scene in Indianapolis.
