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
