Welcome to the HOPE (HIV Outcomes, Prevention and Epidemiology) Group, formerly known as the Duerr Group. Our group, led by Dr. Ann Duerr, uses a highly collaborative and multidisciplinary approach to evaluate prevention and treatment of HIV, with a focus on applicability to high-risk populations in low and middle income countries. We partner with diverse collaborators including laboratory scientists, economists, implementation scientists, and computational biologists to better understand how to prevent new HIV infections, as well as how to put new treatment ideas into action.
