One Health Trust uses research and stakeholder engagement to improve the health and well-being of our planet and its inhabitants. OHT builds on the work of the Center for Disease Dynamics, Economics & Policy (CDDEP), which for more than a decade conducted vitally important research on major global health challenges, including COVID-19, antimicrobial resistance, hospital infections, tuberculosis, malaria, pandemic preparedness and response, vaccination, medical oxygen shortages, and noncommunicable diseases. OHT’s work now expands to take on issues related to climate change, biodiversity protection, and the effect of human diets on the planet. One Health Trust believes that answers to the world’s most critical questions lie between disciplines. Accordingly, OHT researchers employ a range of expertise—economics, epidemiology, disease modeling, risk analysis, clinical and veterinary medicine, geographic information systems, and statistics—to conduct actionable, policy-oriented research. OHT has offices in Washington, D.C., and Bangalore, India, with researchers based in North America, Africa, and Asia. Our projects lead to policy recommendations and scientific studies published in leading journals. We are experienced in addressing country-specific and regional issues as well as global challenges. Our research is renowned for innovative approaches to design and analysis, and we communicate our work to diverse stakeholders.
