Thomas Gillespie.

Thomas Gillespie | Emory University | Atlanta, Georgia, United States

Thomas Gillespie is a disease ecologist and conservation biologist recognized for his integrative approach to the conservation of biodiversity and mitigation of emerging infectious diseases. Gillespie was among the first to demonstrate that human impact on the environment can alter the dynamics of natural pathogens in wildlife and create opportunities for pathogens to jump between species. His efforts serve as demonstration projects of the One Health Approach and have guided international efforts to protect endangered species from human diseases and prevent future pandemics.

Gillespie is a Professor of Environmental Sciences and Environmental Health at Emory University. He co-directs the Gombe Ecosystem Health Project in Tanzania in collaboration with the Jane Goodall Institute and serves as Director of Infectious Disease Research at Centre Valbio in Madagascar. He is an external expert to the UN High Level Political Forum on Sustainable Development, a member of the IUCN/SSC, and a National Geographic Explorer.

Panel Discussion - Climate Change and Development: Implications for Human, Animal and Environmental Health


Climate change will have dramatic yet differential impacts on humans, animals, and the environment. What are the inextricably linked animal, plant, and environmental outcomes of the impacts of climate change? How do these impacts vary globally and how can we leverage One Health to address these entanglements?

Panel Discussion - One Health and Development: Taking Action


We are living in an age of unprecedented anthropogenic global environmental change and seemingly omnipresent public and animal health challenges. These challenges are grand in scale and scope and addressing them at an individual level is not possible. Although action may seem overwhelming, there are many examples of successful One Health and Development initiatives around the globe.

Our panelists will present their stories of how they initiated positive change utilizing a One Health approach and the important lessons they have learned.
