Dr. El-Kamary is a pediatrician and infectious disease epidemiologist. He joined the University of Maryland School of Medicine, Department of Epidemiology and Public Health (D.E.P.H.) and the Department of Pediatrics as an Assistant Professor and was subsequently promoted to a tenured Associate Professor. During his tenure, he conducted research on the epidemiology of hepatitis infections, particularly hepatitis C virus (HCV) infections in Egypt. He studied the incidence, prevalence, and risk factors of HCV in pregnant women and their children, and the immune responses that affect vertical transmission and persistence of infection; and worked with the Center for Vaccine Development to conduct vaccine and therapeutic clinical trials in the US and Egypt. He also attended a weekly pediatric clinic and served as Course Director of an Infectious disease epidemiology course, and as the Director of the M.P.H. Global Health Concentration, and the track leader for the Ph.D. Epidemiology track.

In 2017, he joined the Food and Drug Administration (F.D.A.) as a Medical Officer and Clinical Reviewer at the Division of Antivirals, Office of Infectious Diseases, Center for Drug Evaluation and Research (C.D.E.R.); and continued to teach and attend the pediatric clinic at the University of Maryland as an Adjunct Associate Professor, then as an Adjunct Professor. At the FDA he resumed his work on viral infections by conducting clinical and regulatory reviews of new drug applications and served on several FDA guidance working groups. To date, he was responsible for the approval of several drugs including a drug for the treatment of hepatitis B virus infection, and another one for HIV treatment, in children 2 years and older; the first three drugs for the treatment of HCV infection in children 3 years and older; and recently one of only two available treatments for Ebolavirus infection.

In 2022, he joined Takeda Pharmaceutical Company as a Medical Director in Pharmacovigilance, Marketed Products, Global Medical Safety. In this role, he will apply his significant drug safety experience and his array of expertise in the fields of clinical research, pediatrics, regulatory work, global health, and epidemiology, to review marketed drugs in order to identify safety signals early and avoid potential adverse events in patients. 

Dr. El-Kamary received his medical degree and M.S., from the University of Alexandria, Egypt, and his post-doctoral fellowship training from the Johns Hopkins University School of Medicine, and his M.P.H. from the Johns Hopkins Bloomberg School of Public Health.

Research Interests

Dr. El-Kamary’s research interests are focused on studying the epidemiology and immunology of viral hepatitis infections, particularly in pregnant women and their children. After the introduction of universal hepatitis B vaccination in Egypt, Dr. El-Kamary demosntrated that hepatitis C viral infections (HCV) became the predominant blood borne virus; and that dental care in children was a major risk factor for continued HCV transmission. He also studied the morbidity of acute and chronic hepatitis and conducted clinical trials in Egypt to test allopathic and alternative therapies to alleviate symptoms and treat acute hepatitis infections. In addition to his work on HCV in Egypt, his global health work includes collaborations with several investigators on campus in studies of HIV, poliomyelitis and tuberculosis (TB) in Nigeria.

As a clinician and vaccinologist, he worked with colleagues at the Center for Vaccine Development on several vaccine trials including a safer small pox vaccine, a norovirus vaccine, and an oral anti-diarrheal vaccine derived from enterotoxigenic Escherichia coli.

Dr. El-Kamary's research activities focus on identifying safety signals in drugs, and the use of artificial intelligence and machine learning in the review of adverse reactions to drugs. At the FDA, he explored the association between treatment of HCV infection using directly acting antiviral (DAA) drugs and the concurrent occurrence of herpes zoster infection, which has been a concern in the medical community after the increased use of DAAs in the treatment of HCV infection. After reviewing data at the FDA from 37 clinical trials it was definitively demonstrated that there was no association between the use of DAAs and herpes zoster infection. He also served as the FDA lead investigator on a collaborartive project with UCSF to utilize Machine Learning and Artificial Intelligence to identify safety signals from real world data in physician's clinical notes.
