Dave started his PhD in October 2013, supervised by Sean Rands and Heather Whitney, and has recently passed his viva. His research explored the link between scent and other cues in manipulating bumblebee behaviour.
After finishing his undergraduate degree in Animal Biology at the University of Gloucestershire in 2010, Dave undertook a six-month conservation internship in the Ecuadorian Amazon with the organisation Global Vision International where he primarily worked on surveying the biodiversity of the rainforest fauna. After his internship with GVI, Dave then worked as a Habitat Surveyor for the organisation Operation Wallacea in Mexico where he led surveys in carbon biomass and mammal diversity, as well as taking part in other surveys.
Dave is interested in all aspects of behavioural ecology with a particular enthusiasm for social insects and areas related to conservation. Having mainly worked in field conditions he is excited to get to work in a lab-based environment where the threat of venomous snakes is less prevalent*.
