His research interests are in stereo-chemical aspects of actions of sympathomimetic amines and their blockers. He studied quantitative parameters of drug receptor interactions at the cell membrane, initial components of drug efficacy, and drug antagonism. The study of Ocular Pharmacology and Toxicology interest him greatly. Drug melanin interactions were investigated to explain the long duration of pupillary dilation of atropine like topical medications in light or heavily pigmented iris of eye. His interest also extends to elucidating the unique pharmacologic actions of new substances discovered from plants. He has over 150 peer reviewed publications on these topics. In 1979 he was awarded the Marian Balshone award for teaching the nervous system pharmacology and therapeutics. He has been a member of the American Society of Pharmacology and Experimental Therapeutics. Fellow of the American Association for the Advancement of Science.
