Further details:
My main research interest is neural differential equations (ODEs/CDEs/SDEs). More generally deep learning and time series.
On than that, I enjoy martial arts, ice skating and scuba diving. My supervisor is Professor Terry Lyons.
I am the author of the torchcde and Signatory projects, and a core developer for the torchsde project.
See also my website.
Miscellaneous pieces of work:
- Seminar slides on neural differential equations (An overview of the field)
- Interpolating PDE solutions using feedforward neural networks (Numerical PDE super-resolution)
- Limits of Fisher–KPP equations, branching Brownian motion and a spatial lambda-Fleming–Viot model for population expansion (Stochastic analysis + PDE analysis for modelling population expansion.)
- Polynomial Approximation of Holomorphic Functions (My Master's Dissertation)
