I am willing to supervise PhD students interested in various intersections of topological quantum field theory, double category theory, enriched category theory, metric spaces and other related topics.
If you are interested in applying to work with me you should send me an email (telling me you've read this information!). I will probably suggest you put in a formal application to the department so that you are in the system and can be considered for funding.
You should read carefully the SoMaS information on applying for a PhD place and on funding.
