Expertise
I research how the shape of animal body parts like the lower jaw have evolved to carry out ecological functions like feeding. My PhD is focussed on the variation in jaw shape and function in small insectivorous mammals.

Biography
I am a University of Bristol Palaeontology and Evolution MSci graduate with a range of palaeontological research experience. I have had the pleasure of describing exquisitely preserved early arthropods (trilobites and their relatives) from the Cambrian period to uncover new details about the evolution of this key group and the earliest complex animal ecosystems. This work uncovered the first uncompressed 3D preserved soft tissue in trilobites as well as a new genus and species.
From 2024-2025 I was employed at the University of Bristol researching optimality in the vertebrate lower jaw using a theoretical morphospace approach. This work aims to understand whether the morphologies that have evolved in nature are as well adapted to their function as we tend to assume or if better morphologies could have theoretically evolved.
I am now researching form and function in the jaws of small insectivorous mammals with the aim of improving our understanding of the evolution of the earliest mammals (including our ancestors). I also hope to assess the impact of venom in these animals on their jaw morphologies and muscle systems. The repeated convergent evolution of similar bodyplans across isectivorous mammals is a fascinating phenomenon which my results will help us to understand.

Research interests
Researching the links between form and function in skeletons. Focussed on the skull-jaw system of small insectivorous mammals.
