James Cranch

Hi! I am a mathematician. I teach at the School of Mathematics and Statistics at the University of Sheffield. I have a teaching page there.

Some time ago, I was in the Department of Mathematics at the University of Leicester. I obtained my PhD in 2010, after working with Neil Strickland in Sheffield.

Before that, I did an undergraduate mathematics degree and the Certificate of Advanced Study in Mathematics at Trinity College, Cambridge.
