Short biography

I am a conservation biologist specialising in aquatic ecosystems. My primary research focus is in enhancing knowledge of threatened populations to better inform management.

Currently, I am investigating drivers of population dynamics in European grayling (Thymallus thymallus), including abiotic and biotic impacts on age-specific survival and growth. I am collaborating with Stephen Gregory (GWCT), Richard Cove (Natural Resources Wales), Bob Wellard (The Piscatorial Society), Andy House (Wessex Water) and Rob Britton (Bournemouth University) on this project.

For my PhD project, I worked with both the GWCT Fisheries team and Queen Mary, University of London, studying the role of Ranunculus spp. in chalk stream ecosystems, and its potential application as a management tool for salmonid populations. I am a previous lab member of Dr. Iwan Jones' River Communities group, and Dr. Pavel Kratina's Aquatic Food Web Ecology research group.
