Steffanie Strathdee, Ph.D. is an infectious disease epidemiologist. She is Associate Dean of Global Health Sciences and Harold Simon Distinguished Professor of Medicine at the University of California San Diego, where she now codirects the Center for Innovative Phage Applications and Therapeutics (IPATH). In 2016, Dr. Strathdee and colleagues were credited with saving her husband’s life from a deadly superbug infection using bacteriophages –viruses that attack bacteria. The case, which involved cooperation from three universities, the U.S. Navy, and researchers across the globe, shows how phage therapy can potentially treat multi-drug resistant bacterial infections expected to kill 10 million people per year by 2050. Dr. Strathdee and her husband co-authored their memoir called The Perfect Predator: A Scientist’s Race to Save Her Husband from a Deadly Superbug. For her efforts to revitalize phage therapy in the West, she was named one of TIME magazine’s Most Influential People in Health Care in 2018.
