I am interested in category theoretic modelling of open systems. An introduction to my work can be found on John Baez's blog, my DPhil thesis, or my book An Invitation to Applied Category Theory.

I am an executive editor of Compositionality, and organise the MIT Categories Seminar.

An Invitation to Applied Category Theory

My book (with David Spivak) will be available in Summer 2019.

A course based on this book was taught at MIT in January 2019; videos are available here.
