Department of Zoology



I joined the Department of Zoology in May 2023 as a Research Associate in the Marine Behavioural Ecology Group working with Dr James Herbert-Read. Prior to this I was a Research Associate at the University of Bristol (2018-2021) working with Prof. Christos Ioannou. I obtained my PhD in Biological Sciences from the University of Tasmania in 2017, which was supervised by Prof. Tobias Uller (Lund University) and Dr Geoffrey While (University of Tasmania). I also hold a BA in Biological Sciences and an MSc in Biology (Integrative Bioscience) from the University of Oxford.


I am interested in the drivers and consequences of variation in animal behaviour. I have had the opportunity to work on a range of study systems on topics including sexual selection, phenotypic divergence and animal personality. My most recent research has focused on collective behaviour and decision-making in shoaling fish. My current research with Dr James Herbert-Read is investigating how fish use hydrodynamic motion cues generated by conspecifics, predators, and prey in their movement decision-making.
