Extremely proud of Hannah, Rebecca, Ella, and Robin (not in the photo) who all got awards for their respective posters and talks at the 2025 Department of Biological Sciences Postgraduate Symposium!
Hannah presented some of her PhD results on how oil pollution affects guppy diet and parasitism at the BES Annual Meeting 2024 in Liverpool.
We welcome two new MSc students, Ella Holbrook and Rebecca St Ledger, who will be working on exciting projects related to environmental pollution and environmental gradients.
