I am a computational soft-matter physics academic at the University of Surrey. At the moment I am mainly working on physical aspects of COVID-19 transmission, and with my Surrey colleague Joe Keddie, on how rubber gloves are made. The COVID-19-motivated work is on aspects of transmission. I have also worked on biological physics, especially transport inside cells, and on crystallisation.

For my publications, please take a look at my Google Scholar page. This contains links to pdfs of pretty much all of my published papers.

To the right are excerpts and links to posts on my blog Chance & Necessity. You can take a look at those posts for what I am thinking about at the moment.

I am current group leader of the Soft Matter group in the Department of Physics.

This website is mostly about my research. If you are a Surrey student looking for teaching material, the notes, question sheets etc, for the courses I teach, are on the SurreyLearn modules.

My Erdös number is at most 4.

I should say that the opinions expressed here are my own, and not necessarily those of my employer.
