I am a junior research fellow at Hertford College, University of Oxford. I work on program induction: machine learning computer programs from data. Specifically, I work on inductive logic programming (ILP). I maintain Metagol, an ILP system.

I am looking for students/collaborators to work on ILP, so, if interested, please contact me.
