Mohsen A. Hedaya, PharmD, PhD, is a professor at the Faculty of Pharmacy, Tanta University, Egypt, and is currently on leave to work at the Faculty of Pharmacy, Kuwait University, Kuwait. He received his Bachelor of Science in Pharmacy degree Tanta University, and his Doctor of Pharmacy and Doctor of Philosophy degrees from the University of Minnesota, USA. He joined the College of Pharmacy, Washington State University, USA, in 1993 as an Assistant Professor of Pharmaceutical Sciences. After returning to Egypt in 1999, he was promoted to the rank of associate and then full professor. He served as the Chair of the Clinical Pharmacy Department and Vice Dean for Academic Affairs at the Faculty of Pharmacy, Tanta University.

Dr. Hedaya's area of interest is pharmacokinetics. He has taught basic and advanced pharmacokinetic classes to professional pharmacy students and graduate students in Egypt, the United States, and Kuwait. His research interest includes pharmacokinetic drug interactions, drug delivery to the brain, pharmacokinetic computer simulations, and bioequivalent study design and data analysis. The computer-based and online educational materials developed by Dr. Hedaya in the area of pharmacokinetics are currently being used by more than 350 educational, research, and industrial institutions around the world.
