Me sitting dockside at Peniche, Portugal.
I am a mathematician and teacher, currently a McCain Teaching Postdoc in the Department of Mathematics and Computer Science at Mount Allison University in New Brunswick, Canada.
My main research interests are mathematical physics, topology, and category theory, and in particular, how "higher-algebraic" ideas from category theory can illuminate questions in quantum gravity and the foundations of quantum mechanics. This has connections to Witten-type path-integral invariants for manifolds, combinatorics, representation theory, and more.
Have a look around, and don't forget to visit my blog. Feedback and questions are welcome. Ich kann Ihnen auf Deutsch antworten, et je peux vous répondre en français.(Background photo on all these pages is of the Penrose tile courtyard in front of the new Mathematics building at the University of Oxford, which I took at the Clay Institute workshop held at its opening.)
