Brief Bio and Short CV
I am a logician, mathematician, and informatician. My research is
mainly in logic, where I work in pure logic, including
I am beginning to develop logic-based approaches to a semantic theory of information (in the philosophical spirit of situation theory) from the inferentialist perspective of proof-theoretic semantics. Related to this is a developing interest in ideas from truthmaker semantics and possibility semantics.
I also work in information security, where I work in
While my main research interests lie in the foundations of logic, as described above, my overall perspective unifies these aspects of my work: I am interested in developing foundations, frameworks, theories, and tools for understanding and reasoning about the complex socio-economic-technical systems that define and support our world.
My contributions have been mainly in the following areas: dependent type theory and logical frameworks, including proof theory, semantics, and a unification algorithm; reductive logic and proof-search, including proof theory and semantics, for classical intuitionistic, and substructural logics; categorical models of the classical sequent calculus and its theory of Cut-reduction; the bunched logic BI and its relatives, including proof theory, semantics, algebraic theory, and computational interpretations, and their applications to program logics, including Separation Logic, and security; distributed systems modelling based on resource semantics and process algebra; modal and epistemic bunched logics and layered graph logics, with applications in access control; utility-theoretic concepts in distributed systems modelling and process algebra, with applications in systems security modelling; trust domains; information security economics; the philosophy and methodology of information security; public policy in information security, including information stewardship.
I have broad experience of research, teaching, and management in leading universities and in industry.
Trust me, I'm a logician.
