Jason J. Guo

Assistant Professor


Dr. Guo received his Ph.D. in Pharmaceutical Sciences at the University of Connecticut. His expertise is in the area of drug discovery using biophysical techniques including nuclear magnetic resonance (NMR) and computer modeling. He has been studying the interactions of drug molecules with membranes and the mechanism by which these molecules are transported across the blood brain barrier. Currently, his research focuses on the endocannabinoid system with the emphasis on developing novel molecular probes and potential therapeutics for treating pain, substance abuse and other disorders


Area of Interest

1. Fatty acid binding proteins (FABPs) as potential drug targets
2. Structural determinants of cannabinoid receptors interacting wtih G-proteins
3. Mechanism of drug transport across cell membranes
