Greg received his PhD in behavioural ecology from Bournemouth University (UK) using video experiments and mark-release recapture fieldwork to inform agent-based models, predict the foraging behaviour of fish and ultimately improve river management. After defending his PhD, Greg moved from fish to mosquitoes, working with Philip McCall and others at the Liverpool School of Tropical Medicine (UK) to use machine vision to quantify previously unobserved host-seeking behaviour, as mosquitoes tried to feed on a human under a bednet. These behavioural insights informed the design new bednets, with Greg testing his prototypes under field conditions in Burkina Faso, West Africa, illustrating the value of exploiting an organisms behaviour to improve the performance of control measures. Greg is currently working with Felix Hol, a long-term fellow at CRI and Marie Curie fellow at Institut Pasteur in collaboration with Louis Lambrechts. They are developing new technologies to study mosquito biology and behaviour, focussing on the biting behaviour of Aedes and Anopheles mosquitoes and leveraging these tools to understand the internal and external drivers of mosquito behaviours that are relevant to pathogen transmission.
