Gautam is a Ph.D. student in the College of Pharmacy and Pharmaceutical Sciences at the Washington State University (WSU), Spokane. He is a registered pharmacist in Hyderabad, India. During his master’s, he applied the state-of-the-art physiologically based pharmacokinetic (PBPK) modeling for predicting the effect of CYP2D6 enzyme genetic polymorphism on the pharmacokinetics of its substrate drug Propafenone. His subsequent tenure at Dr. Reddy’s Laboratories Limited, Hyderabad, as a biopharmaceutics scientist for ~2 years further honed his expertise. At Dr. Reddy’s, he was involved in projects on mechanistic prediction of the effect of formulation and manufacturing process variables on the bioavailability and bioequivalence of generic drug products using various PBPK modelling software.
