Profile
Research
I am an animal biologist interested in the organismal biology neurobiology and behaviour of invertebrates particularly insects.
A focus of my research has been to better understand the mechanisms that permit animals to adapt their brains bodies and behaviour to changing environmental conditions. As the principal model I have used the Desert Locust swarms of which periodically devastate agriculture across Africa and Asia. This research programme was funded by the Royal Society the BBSRC and the Leverhulme Trust and has uncovered mechanisms that underpin the transition between the solitary form or 'phase' and the swarming 'gregarious' phase; it has also identified surprising and previously unknown adaptive differences between the two. Active research in animal neuroscience and behaviour discontinued with the University's 'Shaping for Excellence' in 2021.
Research in other aspects of organismal biology includes the physiological plasticity of insects in response to allelochemicals and xenobiotics (collaboration with J. Niven U. Sussex) and the link between structural brain plasticity foraging success and working memory (collaboration with E Leadbeater Royal Holloway).
