I obtained a PhD in Mathematics from the University of Leeds. Since then I have held research and teaching positions at the University of Edinburgh (Laboratory for Foundations of Computer Science), University of Oxford (Department of Computer Science and Keble College), Vienna University of Technology (Institute of Discrete Mathematics and Geometry), and University of Gothenburg (Department of Computer Science and Engineering and Faculty of Philosophy, Linguistics and Theory of Science).
Currently I am Assistant Professor (Universitair Docent) and MacGillavry Fellow at UvA, as well as Assistant Professor (Forskarassistent) at GU.

My research explores the interface of mathematics and computer science by uncovering the subtle interactions between expressibility, complexity, and deductive strength in fixpoint logics. I employ techniques from proof theory, notably proof transformations, cut-elimination and tableaux, to gain insight into the behaviour of fixpoint constructions.
Other topics that I have worked on previously and/or are currently pursuing include relative computability, reverse mathematics, ordinal analysis, computational content of proofs, deep learning, logic of neural networks, automata theory and games.
Together with Yde Venema we have a research team working on Proof Systems for Modal Fixpoint Logics. The project which consists of 1 Postdoc and 3 PhD students commences in September 2019.
