Born and raised in Egypt, Dr. Mary Rezk-Hanna is an Assistant Professor at the University of California, Los Angeles School of Nursing. As the Director of the Integrative Cardiovascular Physiology Laboratory, Dr. Rezk-Hanna’s research interests focus on the cardiovascular health effects and potential harms of conventional, new, and emerging tobacco products and the mechanisms by which these products affect cardiovascular function. Dr. Rezk-Hanna served on the American Heart Association scientific committee that published a scientific statement on hookah (i.e., waterpipe) tobacco smoking and cardiovascular disease risk, as well as the cardiopulmonary impact of electronic cigarettes. Her ultimate goal is to use physiologic data to drive evidence-based policy to regulate novel and alternative tobacco products and nicotine delivery systems. Dr. Rezk-Hanna is a fellow of the American Heart Association and the American Academy of Nursing.
