About Me
I am currently a postdoc mentored by Prof Gesine Reinert, working on applications of Stein's method and topological data analysis to machine learning within the Erlangen AI Hub on the Mathematical Foundations of AI.
Previously, I was a postdoc at Cardiff University in the Geometry, Algebra, Physics, and Topology group of the School of Mathematics, mentored by John Harvey between 2023 - 2025.
I obtained my DPhil in Mathematics at Oxford in 2022 (supervised by Vidit Nanda and Peter Grindrod CBE), as a part of the Industrially Focused Mathematical Modelling CDT.
Further information about my research interests and publication list can be found on my personal webpage:
Research Interests
Topological data analysis (TDA) is about understanding the shape of data. I focus on the following themes within TDA.
- Morse theory (smooth, algebraic, and topological)
- Machine Learning on Graphs and spectral properties
- Data Analysis on non-Euclidean manifolds
- Estimating Properties of Shapes from Samples
