After graduating in 2011 I volunteered at the Game and Wildlife Conservation Trust (GWCT) and worked as a research assistant at Cardiff University in order to acquire practical research experience before beginning my PhD here at Bournemouth under the supervision of Dr Robert Britton.

My initial interests in freshwater biology were sparked during my undergraduate dissertation in which I assessed the potential impacts that deforestation of riparian zones could have on the diversity and abundance of macro-invertebrate fauna within stream ecosystems. My volunteer work at GWCT was part of an international salmon tagging project that aims to map salmon migratory routes and to reveal possible locations for their exploitation. This work led to my involvement with the Diversity in Upland Rivers for Ecosystem Services Sustainability (DURESS) project at Cardiff University, in which I carried out extensive fish population and habitat surveys of rivers across the whole of Wales.

The ultimate aim of my research here at Bournemouth is to develop tools and techniques to improve the accuracy and precision of the fish scale aging process, which is vital in population and growth rate assessments, and then to apply these tools and techniques to collect enhanced data to investigate how disturbances and biotic factors impact the ecology of fish populations and communities.
