Current projects

I currently hold a Career Development Felowship in polymorphic effects at Balliol College Oxford.

I am also currently working with Sam Staton on quantum computation as a programming language thanks to the Engineering and Physical Sciences Research Council and the Royal Society.

I am also currently working with Tom Melham, Sam Staton, Marcin Szymczak, Helen Margetts, and Scott Hale on probabilistic programming in the social sciences thanks to the Alan Turing Institute.

I am also involved with Ehud Lamm’s Conceptual Biology Lab.

Future project

In January 2019 I will move to the University of Edinburgh School of Informatics thanks to a Royal Society University Research Fellowship.
