Summary

 

Summary

My research focuses on rough analysis, deep learning and kernel methods. I am particularly interested in the interplay between neural networks and differential equations, as well as in developing algorithms to extract actionable information from high-dimensional, irregularly-sampled time series.

Prior to joining Imperial, I obtained my PhD from the University of Oxford under the supervision of Prof. Terry Lyons.
