Currently I am a MbyRes student at the University of Exeter investigating the movement of microplastics in benthic ecosystems and determining how interactions with marine biota alters subsequent particle bioavailability. I completed my undergraduate Biological Sciences degree in 2018 and particularly enjoyed the Marine Biology and Ecotoxicology aspects. This led me to pursue a MbyRes in this area of research.

Research projects

Project Title: Plastic Movement Through the Benthic Ecosystem


Dr Ceri Lewis, University of Exeter 

Professor Tamara Galloway, University of Exeter

Project Description: 

The biological processes that transform and transport microplastics to the ocean floor and any accumulation or redistribution that might occur by biological communities once within the benthos are not known, but are of critical importance to understand for assessing risks. 

For my MbyRes, I will look at the movement of microplastics through an experimental marine ecosystem to investigate how species interactions with microplastics, via ingestion and excretion, influence the bioavailability of microplastics to other species and the ultimate fate of plastic particles.
