Dr. Nichar Gregory

Vector Ecologist, Vector-Borne Diseases

"Approximately 80% of the global human population lives in an area at risk from one or more vector-borne diseases. As changing land-use and climate change threaten to intensify global disease burdens, there is an urgent need for creative solutions that transcend traditional disciplines and institutional silos. Through extensive international collaboration and a One Health ethos, EcoHealth Alliance is demonstrating that diversity in philosophies, values and ideas begets innovation, paving the way toward a healthier and more resilient future."

Scientists Bio

Dr. Nichar Gregory joined EcoHealth Alliance in 2022 as the Vector Ecologist on DTRA-funded projects assessing the risk of Rift Valley Fever in South Africa and Crimean-Congo Hemorrhagic Fever in Tanzania. Dr. Gregory’s research focuses on the socio-ecological drivers of vector-borne disease transmission, particularly in understanding how variation in vector biology and diversity shapes transmission dynamics and disease risk. Her research integrates entomological fieldwork, laboratory experiments and mathematical models to develop mechanistic frameworks for predicting vector-borne disease risk in rapidly changing landscapes.

She earned a PhD from Imperial College London, and holds an MA in Ecology, Evolution and Environmental Science from Columbia University, as well as a B.Sc. in Conservation Biology from the University of East Anglia. Prior to joining EcoHealth Alliance, she worked as a Postdoctoral Researcher at Columbia University, where she investigated the eco-epidemiology of tick- and mosquito-borne diseases in New York City.
