Research interests
My current research focus is on the safety and security of machine learning algorithms and autonomous systems. See my LinkedIn page for more details of what I've been up to recently.
My earlier research was is in algebra (category theory and homotopical algebra),
logic (categorical logic and type theory), and
mathematical foundations of computer science (logic in CS and formal
verification).
