Summary

I'm a final year PhD student within the Department of Life Sciences, and am NERC-funded through the Science and Solutions for a Changing Planet DTP at the Grantham Institute.

Before coming to Imperial, I obtained a BSc (Hons) in Biological Sciences from the University of Warwick (2012), and an MSc in Biodiversity and Conservation from the University of Leeds (2015).

I'm supervised by Dr Richard Gill and co-supervised by Dr Samraat Pawar, and am based at Silwood Park campus. Using bumblebees as a study system, my research broadly aims to understand how insect pollinators respond to human-induced environmental change. Increased agricultural practices and intensification have resulted in the addition of harmful chemical pesticides to the environment, combined with the clearance and fragmentation of many natural habitats, posing potential challenges to wildlife such as insect pollinators. Bumblebees are important pollinators, however, as they are central place foragers the increasing rate of floral habitat patchiness is likely to increase foraging distance requirements, making it difficult to sustain a colony's energetic demands. My research aims to gain a clear understanding as to how certain environmental stressors (such as pesticide exposure and climate change / temperature fluctuations) affect bee foraging performance, and the consequences this can have on colony survival under different degrees of habitat fragmentation.
