Profile

After completing my undergraduate studies at the University of Graz Austria with a MSc in Biology/Zoology I moved to the University of Cambridge for my PhD (2000). I held post-doctoral positions at Queen Mary Univ. London and at the University of Sussex elucidating the functional neuroanatomy of nitric oxide signalling in invertebrates. I then secured a Royal Society University Research Fellowship (URF; 2005-14) to research the proximate mechanisms of swarming behaviour in locusts. This took me first back to Cambridge and then in 2013 to the University of Leicester where I was appointed Lecturer in Animal Biology (2014) and promoted to Reader / Associate Professor in 2015. This post became redundant when the University's 'Shaping for Excellence' disinvested from research in animal neurobiology and behaviour and I was redeployed as a teaching-focussed Lecturer in 2021.

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).
