Lewis completed a BSc in Zoology at Cardiff University, and later undertook a ResM project investigating the personality and behaviour of two species of primates. Following graduation from his BSc Lewis worked in different roles across several UK Zoos including in the fields of animal management and welfare, before moving to the Zoological Society of London (ZSL) in 2017. Since that time, he has worked within zoo science roles and now as the Zoo Research Officer for ZSL has responsibility for the coordination of research activities that take place at both ZSL London and Whipsnade Zoos. As part of this role, as well as his position on the BIAZA (British and Irish Association of Zoos and Aquariums) Research Committee Lewis is interested in facilitating scientific practice in zoos; both to inform evidence-based animal care, but also to contribute to the role of modern zoos in the advancement of scientific knowledge.
Joining the SWC PhD programme in 2021, Lewis now works with Tiago Branco and Troy Margrie on a project based at the ZSL Zoos to compare spatial learning and navigation strategies across taxa. This work will involve tracking freely moving animals within naturalistic environments, in response to resource location and cognitive challenges.
