Overview
I graduated from Bangor University with a bachelors degree in Applied Marine Biology where my research focused primarily on aquatic ecology and oceanography, with a final year project on the imact of a tidal turbine on fish schools. As part of my undergraduate degree I undertook a placement year here at Cardiff with the Fish Hives Project in which I was responsible for managing the data collection and analysis of artifical coral reef structures. This connection then enabled me to do my Mres at Cardiff University studying the impacts of microplastics on fish welfare and disease.
As part of the OneZoo CDT my PhD project is investigating the impact that pharmaceuticals have on the environment and fish health in a multi-disciplinary collaboration with the Schools of Chemistry, Bioscience and Engineering. I am supervised by Dr Ben Ward, Prof Jo Cable, Prof Devin Sapsford from Cardiff University, Prof Luis Mur from Aberystwyth University and my stakeholder Dr Dan Read from the UK Centre for Ecology and Hydrology.
