About Samuel Obeng

Samuel Obeng, Ph.D., was appointed as an assistant scientist in the College of Pharmacy, Department of Pharmacodynamics in July 2019. Obeng received his Bachelor of Pharmacy and M.Phil. Pharmaceutical Chemistry degrees from Kwame Nkrumah University of Science and Technology, and his Ph.D. in Medicinal Chemistry from Virginia Commonwealth University, Department of Medicinal Chemistry. Upon completion of his doctoral studies, Obeng completed a 1-year postdoctoral fellowship under the supervision of Dr. Yan Zhang and Dr. Dana Selley in the Departments of Medicinal Chemistry and of Pharmacology and Toxicology at Virginia Commonwealth University. Obeng then joined the University of Florida College of Pharmacy in July 2018 as a postdoctoral research associate in the Department of Pharmacodynamics working in both Dr. Lance McMahon and Dr. Christopher McCurdy’s laboratories. Obeng has keen interest in the design, discovery and development of novel opioid ligands for the treatment of pain and opioid use disorder.
