Dr. Khaled A. Elsaid joined CUSP on August 1, 2016 as a tenure-track associate professor of pharmacology and was awarded tenure in May 2019. Dr. Elsaid graduated with a Bachelor of Science in Pharmaceutical Sciences from Cairo University in 1997. He traveled to the U.S. for his graduate education at the University of Rhode Island (URI) in 1999. Over a 6-year period (1999-2005), he earned an MS in Biomedical Sciences, a Ph.D. in Pharmacology and Toxicology, and a Master’s in Business Administration (MBA). After graduation, Dr. Elsaid worked as a research associate
As a clinician-scientist, Dr. Elsaid has active research programs in translational pharmacology and practice-based research.
