I started working in EMD Serono (Merck KGaA) as Head of Signal Detection and Benefit Risk Assessment in 2017. Prior to that, I worked in Merck (MSD) as an Executive Director of pharmacoepidemiology in 2013. Previously, I was the Deputy Division Director of one of the Epidemiology Divisions located in the Office of Surveillance and Epidemiology (OSE) in the Center for Drug Evaluation and Research (CDER). In 2000, I joined the Divisions of Neurology and Psychiatry Drug Products in CDER as a drug safety Medical Reviewer and served as an active member of a multidisciplinary team which had the overall responsibility for pre- and post-marketing safety evaluation of neurology and psychiatry drugs. Subsequently, in 2004, I joined OSE as a Senior Medical Epidemiologist to work on large electronic medical records and insurance claims databases assessing post-marketing safety issues. From 2006 to 2011, I was serving as the Analytic Epidemiology Team Leader and, more recently, as the Associate Director of Epidemiology in OSE.

I hold a Ph.D. in Epidemiology (1996) and a Master of Science in Preventive Medicine (1993), both from the University of Maryland. Subsequently, I obtained my medical certification from the US ECFMG (1998). Prior to that, I received my medical degree from Cairo University School of Medicine (1986) and a Master of Science in basic medical sciences from Minya University School of Medicine (1991), both in Egypt. I have authored many peer-reviewed publications and made many national and international presentations in various scientific conferences and other settings. I also hold several academic appointments spanning various medical disciplines.
