I am a behavioral scientist with multidisciplinary training from the fields of public health, psychology, and sociology. Broadly, my research seeks to understand and intervene upon family health related to HIV/AIDS, alcohol use, cardio-metabolic disorders, diet, and mental health. Specifically, I am interested in dyadic aspects of health within primary partnerships. My research is grounded in theory from the field of relationship science, and employs mixed-methods and dyadic analysis techniques to understand and intervene upon couple-level health behavior. My research takes place in the United States and Southern Africa with couples at risk and living with HIV. My primary area of research consists of a set of trials to develop and evaluate couple-based approaches to reduce heavy alcohol use in South Africa, Malawi, and the U.S. My secondary line of research study focuses on understanding multi-morbidity disease management in couples living with HIV and cardiometabolic disorders. My third area of research develops and evaluates couple-based interventions for perinatal depression using problem-solving therapy. I am also involved in other global health projects including an RCT of a couple-based intervention to increase engagement in HIV treatment in South Africa, and the evaluation of an agricultural livelihood intervention in Kenya. My program of research is funded by a diverse set of NIH institutes including the NIMH, NIAAA, and NHLBI and has led to around 70 publications in top journals.
