My research is primarily focused on improving HIV and TB outcomes in low and middle income settings, primarily in Southern Africa. My work spans implementation science, patient behavior, and outcomes research. The overall goal it to identify gaps in service delivery leading to increased mortality and to test intervention or implementation strategies to overcome these gaps. This work additionally draws from behavioral economics and social psychology. The populations that I work with are the general urban, peri-urban, and and rural populations as well as incarcerated and re-entry populations. My current work is in South Africa, Mozambique, Malawi, Zimbabwe, and Maryland.
