Helena Chapman is a Professorial Lecturer in the Department of Environmental and Occupational Health at the Milken Institute School of Public Health at the George Washington University. She also supports the NASA Applied Sciences Program (Booz Allen Hamilton) as Associate Program Manager for Health and Air Quality Applications. In this focus area, her team promotes the use of Earth observation data in public health applications, related to air quality management and infectious disease prevention and control. She also serves as the Executive Coordinator of the GEO Health Community of Practice and Earth Observations for Health (EO4Health) Initiative. Prior to this position, she was a AAAS Science & Technology Policy Fellow in the NASA Applied Sciences Program. She also was a Christine Mirzayan Science & Technology Policy Fellow at the National Academies of Sciences, Engineering, and Medicine, where she worked on the Veterans and Agent Orange: 11th Biennial Update consensus study.

Trained in medicine, epidemiology, and environmental health (One Health), Dr. Helena Chapman is passionate about promoting transdisciplinary health collaborations that investigate and mitigate health risks of humans, animals, and ecosystems. By integrating social science concepts and the One Health approach, her research has examined the determinants of health that influence risk associated with tuberculosis and dengue transmission in Cuba, Dominican Republic, and Puerto Rico. Her dissertation research examined the "knowledge-action" gap among health care workers regarding adherence to tuberculosis infection control measures in tertiary-level health institutions in the Dominican Republic.

Her global health practice activities focus on building capacity for health professions education and training programs that prepare the global health workforce to better understand and mitigate environmental health risks across all communities. She was founding member and current advisor of the first Dominican Republic (non-governmental) medical student organization (Organización Dominicana de Estudiantes de Medicina, ODEM), with the primary mission to strengthen medical students’ collaborations focusing on leadership, research, and health education outreach across communities in the Dominican Republic. She serves as the Editor in Chief of the World Medical Journal (official journal of the World Medical Association) and previously as the Publications Director of the Junior Doctors Network, where she encouraged junior doctors to share their local, national, and international leadership and professional activities with the global audience. She currently is a member of the One Health Initiative Autonomous pro bono team and leader of the One Health Commission's One Health Social Sciences Initiative

She received her PhD in Public Health (One Health) and MPH in Epidemiology from the University of Florida. She holds an MD from the Iberoamerican University in the Dominican Republic.

Dr. Chapman's research interests focus on strengthening global health education, practice, and research related to the prevention and management of tropical infectious diseases in Latin America and the Caribbean. By integrating social science concepts and the One Health approach, her research has examined the determinants of health that influence risk associated with tuberculosis and dengue transmission in Cuba, Dominican Republic, and Puerto Rico. Her global health practice activities focus on building capacity for health professions education and training programs that prepare the global health workforce to better understand and mitigate environmental health risks across all communities.

Her previous research studies have integrated qualitative research methods to explore health workers’ perceived challenges for dengue prevention and control strategies in the Dominican Republic. Study findings highlighted the complex interplay of economic, environmental, health, political, and social factors that influenced individual and community adherence to recommended dengue and tuberculosis prevention and control measures.

Dr. Chapman's current research and community practice interests include: 

  • Exploring the “Knowledge-Action” Gap among Health Workers on Adherence to Infectious Disease Prevention and Control Practices
  • Strengthening Health Professions Education and Training in Latin America and the Caribbean
  • Understanding Veterans' Physical and Psychosocial Health Concerns related to Post-deployment Reintegration
  • Using Satellite Data and Citizen Science Applications to Examine Ecosystem Changes, Zoonotic Disease Research, and One Health Education
