Professional background: I read Computer Science at the University of Oxford and completed my DPhil (PhD equivalent) in 2017. Following that, I moved to New England to work at Wesleyan University as a postdoc in Homotopy Type Theory.

Personal interests: I am interested in the logical foundations of programming languages and computing at large. My work is driven by the possibility of applying what is normally thought of as very pure mathematics to the clarification of various concepts and situations found in programming and informatics. My current research is mostly centred around the applications of modal logic and modal type theory to programming languages. Modalities can express various data flow properties, leading to very strong systems for static typing. The intended applications range from the purely mathematical (e.g. more succinct and informative mechanised proofs of theorems in topology) to the very applied (for example, the control of information flow in language-based security).
