About me

I am a PhD student at the University of Warwick, supervised by Mark Steel. My research develops methods for causal inference under model uncertainty, often from a Bayesian or post-Bayesian perspective. I am particularly interested in making causal inference more robust by explicitly accounting for uncertainty about the assumptions it relies on.

From September 2025 to February 2026, I was a visiting researcher at Nanyang Technological University Singapore, hosted by Jeremie Houssineau, where I worked on causal inference through the lens of possibility theory.

I will be on the job market for postdoc or industry research positions in 2027. Feel free to get in touch if you think I might be a good fit.
