Dr. Troy T. Rohn obtained his Ph.D. in pharmacology from the University of Washington, Department of Pharmacology in 1994. He completed postdoctoral stints at INSERM (Paris, France), Montana State University, and the Institute for Memory Impairments and Neurological Disorders at UC Irvine. Currently, Dr. Rohn is a professor in the Department of Biological Sciences at Boise State University where he has taught and performed research for the past 19 years. His research focuses on the role that certain proteases play in promoting the pathology associated with different neurodegenerative diseases. More recently, his research has focused on how the ApoE4 protein enhances AD risk at the molecular level. Harboring the APOE4 gene is the single greatest genetic risk factor for late-onset AD.
