I am Scientist in Residence at the School of the Art Institute of Chicago, Honorary Fellow of the University of Sheffield and Honorary Visiting Fellow of City University, London. Previously I was a Senior Lecturer (Associate Professor) of Pure Mathematics in the School of Mathematics and Statistics, University of Sheffield, UK.  From September 2013 to December 2014 I was a visiting Senior Lecturer at the University of Chicago and I have been based in Chicago ever since, though I still frequently work and give talks in Europe.


My research is in category theory, mostly higher-dimensional. Some non-technical introductions to my field can be found here. I am author of the popular mathematics book "How to Bake Pi: An Edible Exploration of the Mathematics of Mathematics" published by Basic Books (UK titke: "Cakes, Custard and Category Theory: easy recipes for complex maths", published by Profile.) Here is the New York Times review. my appearance on the Late Show with Stephen Colbert, and a feature about me and my work in the New York Times Science section. The book is being translated into six languages so far.

I am keen to bring mathematics to a wider audience and help reduce maths phobia!  I am good at explaining things in an accessible way to non-mathematicians of all ages.  I am happy to discuss or comment on most aspects of mathematics, universities, education, gender and cultural issues.  For more information including sample video and audio and clips, please click here.  


Until September 2007 I was a Marie Curie Fellow at the Laboratoire J. A. Dieudonné, the Department of Mathematics at the Université de Nice-Sophia Antipolis.
From 2004 to 2006 I was an L. E. Dickson Instructor in the Department of MathematicsUniversity of Chicago.
From 2001 to 2004 I was a research fellow in pure mathematics at Newnham CollegeCambridge.
Before arriving at Newnham College, I was at Gonville and Caius College, where I did my Ph.D., Part III and undergraduate degree.
