Research and Professional Experience

Dr. Omer has worked on research studies in the United States, Guatemala, Ethiopia, India, Pakistan, Uganda and South Africa.

He has been involved in conducting vaccine trials and large-scale surveillance of vaccine preventable diseases. Dr. Omer and his colleagues have conducted several studies to evaluate the roles of schools, parents, health care providers, and state-level legislation in relation to immunization coverage and disease incidence. He has conducted research and performed policy analysis on public health preparedness including pandemic influenza preparedness and has worked on identifying and addressing deficiencies in preparedness of the American public health workforce.

Dr. Omer has also been working on clinical trials of drug regimens to make breastfeeding safe for infants of HIV positive mothers in Africa and on strategies to ensure adherence to anti-HIV therapy.

Keywords
