Overview

My research lies at the interface between Mathematics and Data Science, and focuses on the design and analysis of problem-dependent data-driven learning strategies. I am specially interested in the exploration of the connections between Machine Learning and traditional knowledges in Mathematics, with the aim of developing theoretically sound and numerically efficient learning strategies having the ability to tackle large-scale and complex problems.

Research

To date, my research has focused on the following topics: 

  • kernel methods,
  • random-field models, 
  • spectral methods in machine learning,  
  • design of experiments, 
  • approximation of integral operators, 
  • sparse approximation,
  • kernel discrepancies.

Teaching

I am a Fellow of The Higher Education Academy (since 2019). 

Currently taught courses (2020/21): 

  • Multivariate Data Analysis (Year 3, MA3506)
  • Foundations of Statistics and Data Science  (MSc, MAT022)

Supervision of project students: Every academic year, I propose and supervise a selection of projects on various topics. If you are currently studying Mathematics at Cardiff University and consider doing a project on a topic related to the Mathematics of Data Science, please feel free to contact me.
