About

Gavin is a freshwater ecologist, investigating the effects of extreme events upon stream and river structure and functioning. Whilst interested in climate change and biotic responses, Gavin’s research looks beyond ‘mean’ climate changes and focuses upon extreme events, specifically drought and heat waves. 

This research follows recent IPCC publications outlining the threat from extreme events to aquatic systems. Gavin uses laboratory microcosm and field mesocosm experimental approaches in order to manipulate biotic and abiotic stressors whilst being able to control all other environmental parameters. The research ranges from single species to community responses, and includes multiple stressor impacts.

Gavin is part of a collaborative research project entitled DriStream, which encompasses the University of Birmingham, Queen Mary University of London and Imperial College London. The project is funded by the UK National Environment Research Council (NERC) and led by Dr Mark Ledger.

Gavin is also the Freshwater Student Representative for the British Ecological Society (BES) Aquatic Group and has been responsible for organising the group’s 2014 conference event. Gavin’s role includes helping the group achieve its numerous aims and to support and represent Early Career Researchers. 

Qualifications

  • BSc Environmental Science (2011) First Class Honours

Biography

Gavin moved from the rural countryside of Herefordshire to study BSc Environmental Science at the University of Birmingham, which he passed with a first class honours. Gavin then worked as an Environmental Technician for a soil and groundwater remediation company where he trained towards becoming a remediation site scientist on a prestigious Longbridge development site, and a pharmaceutical site in Dartford. Gavin then returned to the University of Birmingham to undertake doctoral research and is currently reading for a PhD in freshwater ecology. 

Teaching

Gavin demonstrates on a BSc Environmental Science first year field course and a second year aquatic ecology field course. Gavin also undertakes invigilating and marking.

Other responsibilities include co supervision of BSc and MSc dissertation projects.
