Dr. Omar El-Halfawy


Dr. El-Halfawy is a Canada Research Chair in Chemogenomics and Antimicrobial Research and an Assistant Professor of Biochemistry at the University of Regina.

Originally from Egypt, El-Halfawy received his B.Sc. in Pharmaceutical Sciences from the Faculty of Pharmacy, Alexandria University in 2005. After working as a Community Pharmacist, he returned to academia and received his M.Sc. in Pharmaceutical Microbiology from Alexandria University in 2009.

In 2010, he moved to Canada and completed his Ph.D. in Microbiology and Immunology at the University of Western Ontario in Dr. Miguel Valvano’s lab, focusing on mechanisms of intrinsic antibiotic resistance mediated by metabolites and other bacterial small molecules.

In 2015, El-Halfawy started a postdoctoral fellowship in Dr. Eric Brown’s Lab at the Department of Biochemistry and Biomedical Sciences and the M.G. DeGroote Institute for Infectious Disease Research, McMaster University, where he explored novel solutions to target multi-drug resistant bacteria.

In 2020, El-Halfawy received a prestigious Canada Research Chair award and started his independent research group at the University of Regina. His research group is actively working towards solutions for the current antibiotic crisis. His group uses a wide range of approaches spanning microbiology, biochemistry, molecular biology, chemical biology, and chemogenomics to uncover novel antibiotic resistance and microbial virulence mechanisms, and discover new antimicrobial strategies.
