The Eco-Epidemiology Research Group currently consists of two research units that conduct fundamental and applied research at the interface between pathogen, vector, host and environment: Entomology and Helminthology. In a global context, many infectious diseases continue to emerge or re-emerge with unexpected distributions and unprecedented intensities, while other (endemic) infectious diseases persist. Recognising that pathogen, vector, animal and human host populations interact with each other and with the environment, this Research Group applies a whole system approach (One Health, Eco-health) to understand the transmission and to improve the prevention, control, and/or elimination of infectious diseases. This is done by interdisciplinary research, combining field epidemiology and ecology with lab-based research and modelling. The focus is on neglected tropical diseases (NTDs) and malaria, with specific emphasis on vector-borne diseases, zoonoses and parasitic (co-)infections.
