Bio
Dr. Neubig received his B.S. in chemistry from the University of Michigan, M.D. from Harvard Medical School in the Harvard-MIT Program in Health Sciences and Technology, and Ph.D. in pharmacology from Harvard University. He trained in internal medicine at University of Michigan Hospitals then joined the faculty in the departments of Pharmacology and Internal Medicine (Hypertension Division) from 1984-2013. He was Chair of Pharmacology & Toxicology at Michigan State University from 2013-2021 and is now Professor of Pharmacology & Toxicology and Director of MSU Drug Discovery. He has studied GPCR signaling for most of his career and is currently testing gene therapies for G protein disorders that result in movement disorders and epilepsy. Since 2000, he has had a major focus on academic drug discovery. He founded the Center for Chemical Genomics at the University of Michigan and MSU Drug Discovery at Michigan State University. His own efforts in drug discovery have focused on cancer, scleroderma, and other fibrotic diseases. He was the co-founder of a start-up company FibrosIX Inc. He was the founding chair of the ASPET Division of Molecular Pharmacology, President of ASPET in 2013-2014 and is a Fellow of ASPET (FASPET). He received both the Astellas and ASPET-Pharmacia awards for translational pharmacology. He has been active in international pharmacology having served on the IUPHAR Receptor Nomenclature Committee from 2000-2015 for which he was GPCR co-chair. He is a Fellow of the American Association for the Advancement of Science (AAAS) and is past chair of Section S, Pharmaceutical Sciences of AAAS. He is an active birder and loves being out in nature and is always thrilled to be with his grandchildren (ages 0, 2 and 6).Lab Staff
