William Reidy, PhD, MPH
- Assistant Professor of Epidemiology (in ICAP) at the Columbia University Medical Center
Overview
William Reidy is an epidemiologist whose focus at the Mailman School includes both implementation science research and supporting the global scale-up of HIV/AIDS prevention and medical care services. Dr. Reidy has worked as an investigator or in a strategic information role on projects in numerous countries including Swaziland, Kenya, Myanmar, Tanzania, and South Africa. His strategic information support of program scale-up has aimed to strengthen systems for provision of HIV medical care, prevention of mother-to-child transmission of HIV (PMTCT), HIV testing and counseling, and HIV prevention programs for key populations, including pre-exposure prophylaxis. Dr. Reidy's research has examined the performance of HIV medical care and PMTCT models during scale-up and factors related to successful patient outcomes.

Global Health Activities
Safe Generations - Plus: Safe Generations-Plus is implementation science study funded by the National Institutes of Health which aims to understand how to improve retention in care and treatment services for HIV-positive pregnant women and their babies in Swaziland. In this study we are assessing outcomes of patients who were lost to follow-up from care under a new approach for prevention of mother-to-child (PMTCT) called Option B+, where all HIV positive pregnant women initiate lifelong antiretroviral therapy (ART) regardless of their health status. The goal is to understand the outcomes of patients who are lost to follow-up from care, and the reasons for disengagement from care in the context of Option B+ in order to inform efforts to improve retention in care and patient outcomes.
