Sush Majumdar received his PhD in Medicinal Chemistry from University of Florida, FL and a Post-doc in Neuropharmacology from Sloan Kettering Cancer Center, NY. He is a Faculty in the Department of Neurology at Sloan Kettering. Research in the Majumdar laboratory is aimed at attaining functional selectivity of opioid agonist action from its on target adverse effects while integrating chemical synthesis with biochemical, genetic and pharmacological approaches. Work from the laboratory has led to probes which display G-protein biased signaling, transmembrane splice variants of mu opioid receptor agonists and aided the crystallization of kappa opioid receptor in its active form.
