Personal profile


Tim Mercer is the director of global health at Dell Medical School and an assistant professor in the Departments of Population Health and Internal Medicine. He is a primary care physician for the Healthcare for the Homeless program with CommUnityCare, Austin's largest federally qualified health center. Fundamentally, he is interested in addressing the root social, economic and structural causes of poor health outcomes, and solving health system challenges to improve access, quality and equity in health for vulnerable populations globally.

Mercer studied biology and philosophy at Butler University in Indianapolis, Indiana. He received a Masters in Public Health (MPH) with a focus in social and behavioral sciences from the Yale School of Public Health and a medical degree from Indiana University School of Medicine. He completed a combined internal medicine and pediatrics residency at Duke University Medical Center.

Mercer has done extensive work in Eldoret, Kenya, where he served as the medicine team leader for the Academic Model Providing Access to Healthcare (AMPATH). AMPATH is a collaboration between Moi Teaching and Referral Hospital (MTRH) and Moi University School of Medicine in Kenya, and a consortium of 13 North American academic medical centers led by Indiana University. He held joint faculty positions in the departments of Medicine at Indiana University School of Medicine and Moi University School of Medicine. He lived full-time in Kenya, where he practiced general internal medicine, pediatrics and HIV care. He also coordinated U.S. medical student and resident global health rotations, taught U.S. and Kenyan medical students and residents, conducted health systems research and implemented quality improvement programs. He is co-investigator on a five-year National Heart Lung and Blood Institute implementation science grant to test a multifaceted intervention designed to strengthen referral networks for hypertension care across western Kenya.

At Dell Medical School, Mercer leads the development of the global health program. Under his leadership, Dell Med has joined the AMPATH Consortium in Kenya. He is also seeking to establish a long-term, mutually beneficial, bilateral partnership with a medical school in Latin America to engage across the trifold academic mission of service, teaching and research to strengthen health systems and improve health outcomes for low-income people. He is also engaging faculty members from across the campus of The University of Texas at Austin in global health work.
