Professional Interests
| My research activities are
interfacing the areas of artificial intelligence, philosophy,
mathematics, computer science, and natural
language. Current research focuses on the use of formal
argumentation & explanation to achieve trustworthy AI systems, that
is reasonable machines.
I am particularly
interested in the use of classical higher-order
logic (HOL) as a universal meta-logic to
automate various non-classical logics and to utilise them in topical application areas,
including machine ethics & machine law, metaphysics (e.g. Gödel's
ontological argument), mathematical foundations (e.g. category
theory) and rational
argumentation. My research
activities also
address the integration of automated reasoning, machine
learning and agent-based architectures. I have a core
expertise in classical higher-order logic (HOL), and I have contributed to its
semantics and proof theory, and together with colleagues and
students I have developed the Leo theorem provers for HOL.
