Batya Elul, PhD, MSc, has over 20 years of experience conducting applied research on HIV and reproductive health in resource-limited settings. Since 2005, her research has focused on optimizing outcomes across the HIV care continuum in the context of massive and rapid scale-up of HIV services in sub-Saharan Africa under the US President’s Emergency Plan for AIDS Relief (PEPFAR). She has a particular interest in the use of patient-level and aggregate data collected routinely as part of HIV service scale-up to answer pressing implementation science questions. From 2010-2014, she was the Director of Strategic Information at ICAP ( where she led efforts to collect, manage, analyze and disseminate data on over 2.1 million people living with HIV enrolled in HIV care at 4,000 PEPFAR-supported clinics. In recent years, her research has focused on identifying modifiable health service delivery factors associated with improved outcomes across the HIV care continuum, and on developing and evaluating new models of HIV care using cluster randomized designs. She is currently exploring the potential for integration of adolescent-friendly services to improve outcomes among adolescents living with HIV. Prior to joining Columbia’s Mailman School, Dr. Elul was a Program Associate at the Population Council in New York and New Delhi where she was responsible for clinical, social science, and community-based research and evaluation on reproductive health issues in Asia and North Africa. Much of that work focused on making reproductive health technologies more accessible to women and simpler to access in resource-limited settings. Her research has been funded by NIH, CDC, USAID and private foundations.
