Andrew Cropper

I am a research fellow in the computer science department at the University of Oxford. I work on logic and machine learning, i.e. inductive logic programming. I run the Logic and Learning (LoL) group and the The Automatic Computer Scientist (AutoCS) project. I develop Popper, an ILP system.

I am looking for DPhil (PhD) students to join me in Autumn of 2022/2023. If interested, please email me.

I will recruit multiple postdocs in 2022, 2023, and 2024 to work on the AutoCS project. I am looking for at least one expert in constraint satisfaction problems (SAT/ASP/CP). If interested, please email me.
