Tim Button (he) is a Professor of Philosophy & Logic at UCL.

I work at the area where philosophy meets logic and mathematics. You can read some short words about my research, or watch me elaborate on them in my inaugural lecture (from December 2024).

Most of my research right now is on theoretical equivalence, types, and sets. I fairly recently published a serialized trilogy on Level Theory, and the trilogy continues to expand. (It now has six parts, with more in the pipeline.)

Sean Walsh and I published Philosophy and Model Theory (OUP, 2018). My first book was The Limits of Realism (OUP, 2013). I have made some open education resources.

James Wilson and I are the joint editors of MIND. I am currently the Head of the Philosophy Department at UCL, but my last day is on 30 August.

This is my main site; it gives you access to free pre-prints (or better) of all my papers. Still, here’s my academic social media roll:
