I am a Professor in the Social and Behavioral Interventions Program in the Department of International Health, Johns Hopkins Bloomberg School of Public Health. I teach courses on qualitative and formative research and applied medical anthropology. My research focus is on 1) improving the health of mothers and children in areas where access to health facilities is poor or non-existent, and 2) behavior change interventions and health system responses to global environmental threats. My work examines design and implementation of primary health care interventions in low and middle-income countries, and development and evaluation of behavior change interventions.

I am the leader for the "Healthier Environment" thematic area in the university-wide "Alliance for a Healthier World", see

My research is grouped into 5 topical areas: (1) Applied social science and vector-borne disease control - I have examined the application of social science theory and methods to the control of infectious diseases, especially vector-borne diseases such as malaria, dengue hemorrhagic fever and schistosomiasis. (2) Community health workers - I have a long-standing interest in community health workers (CHWs) as a strategy for delivering interventions to populations living far from health facilities. (3) Implementation of maternal, newborn and child health interventions - Building on Topic 1, I have examined the application of social science theory and methods to the design and evaluation of maternal and newborn health interventions. (4) Behavior change interventions for water, sanitation and hygiene (WASH) - Building again on Topic 1, I have examined the application of social science theory and methods to the design and evaluation of interventions to promote WASH behaviors including handwashing with soap at key times, home water treatment, and latrine use. (5) Climate change adaptation - I am highly engaged in efforts to respond to climate change as a faculty member at Johns Hopkins University. I serve as Co-Coordinator of the MPH Concentration in Global Environmental Sustainability and Health, an academic track which offers a comprehensive set of courses on climate change, food security, energy policy and the built environment, and work closely with the JHU Energy, Environment, Sustainability and Health Institute (
