I am currently spending one day a week on a secondment with EOLAS Insight working on exploring the use of different machine learning methods in remote sensing.

Please get in touch via email if you are interested in doing a PhD with me.

About

I am a lecturer in machine learning in the School of Mathematics, University of Edinburgh.

Before joining the School of Mathematics in Edinburgh, I was a PhD student at the Cantab Capital Institute for the Mathematics of Information (CCIMI) and the Statistical Laboratory within the Department of Pure Mathematics and Mathematical Statistics (DPMMS) at the University of Cambridge, supervised by Dr Sumeetpal S Singh. In April 2021, I moved to the University of Edinburgh with a LMS Early Career Fellowship, and became a postdoctoral research assistant working with Dr Tim I Cannings in May 2021. I started my current position in September 2023.

Academic Activities

I am a member of the Royal Statistical Society, the International Society for Bayesian Analysis and the Institute for Mathematical Statistics.

I enjoy reviewing papers within my area of expertise.

Miscellaneous

I love sailing and wrote a (hopefully) entertaining logbook entry about the first half of my summer sails 2022 and a logbook ballad about my summer sail 2023.
