I am a post-doctoral researcher in the complex systems group of the Max Planck Institute for Mathematics in the Sciences in Leipzig, Germany, where I am applying category theory to game theory and more general economics. My long-term aim is to work towards large scale economic applications where existing methods are impractical to apply.
Scalability is the end, compositionality is the means, category theory is the means to the means.
Other topics I am interested in include logic (especially constructive and linear logic), functional programming, and the semantics of natural language.
You can find an updated bibliography of all things related to compositional game theory here.
For an introduction to the philosophy behind my research, see
If you are coming to compositional game theory for the first time and want to know where to start, see my reading list
You can watch me giving an introductory lecture on open games here (starts around 1:30).
