Brief Bio and Short CV
I am a logician, mathematician, and computer scientist. My research is
mainly in logic, where I work in pure logic, including
I also work in information security, where I work in
My overall perspective unifies these aspects of my work: I am interested in developing frameworks, theories, and tools for understanding and reasoning about the complex socioeconomictechnical 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 proofsearch, including proof theory and semantics, for classical intuitionistic, and substructural logics; categorical models of the classical sequent calculus and its theory of Cutreduction; 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; utilitytheoretic 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.

  prooftheoretic semantics, also known as the theory of meaning, and
  the proof theory and semantics of reductive logic (see, for example, Reductive Logic:
 Proof Theory, Semantics, and Control, by David Pym and Eike Ritter,
 Oxford Logic Guides and the EPSRCfunded project ReLiC )
I also work in information security, where I work in
  security policy,
  security economics, and
  systems security modelling,
