Dr. Olgun Guvench joined the UNE College of Pharmacy as Assistant Professor in the Department of Pharmaceutical Sciences in July of 2009. Before joining UNE, Dr. Guvench was a National Institutes of Health Kirschstein Postdoctoral Fellow at the University of Maryland, where he trained in biomolecular simulation and structure-based discovery/design, including developing new atomic-resolution models for simulating carbohydrates. Prior to his postdoctoral training, Dr. Guvench earned a Ph.D. (2005) from the Scripps Research Institute, with a thesis titled "Theoretical Studies of Proteins and Protein-Ligand Complexes," an M.D. (2001) from Columbia University, and an undergraduate degree in chemistry from Harvard University (1997). Dr. Guvench teaches biomedical sciences to Pharm.D. students and pursues research in the fields of biomolecular simulation, with a focus on protein-carbohydrate interactions.
