I am Professor in the Social and Behavioral Interventions (SBI) Program in the Department of International Health, Johns Hopkins Bloomberg School of Public Health. I have a longstanding commitment to training of public health professionals. I have been teaching since 1988, have served as academic advisor for over 100 graduate students, and teach courses on global health, qualitative and formative research, design of facility and community-based behavior change interventions for health and environmental sustainability, and applied medical anthropology. The main focus of my work is community engagement in health, behavior change interventions, and qualitative and formative research. My current areas of research include 1) Behavior change interventions for infectious diseases, environmental sustainability, and water, sanitation and hygiene (WASH); 2) Interventions for facility and community-based health care providers to improve quality of assessment, treatment and adherence to testing and treatment recommendations; 3) Implementation of facility and community-based maternal, newborn and child health interventions, maternal mental health; 4) Community and policy interventions to reduce greenhouse gases and criteria air pollutants; and 5) Youth opportunities, outdoor education and delinquency prevention.

I am co-chair of the university-wide Sustainability Leadership Council (SLC). The charge of the SLC is to provide advice and recommendations to the Provost on policies, programs, and other initiatives that will build a greater role for Johns Hopkins in teaching, research, and leadership on environmental sustainability, both locally and globally. It is also tasked with amplifying the University’s research and practice around environmental sustainability, through fostering academic collaboration and supporting the work of the Office of Sustainability.

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 (
