About

Overview

My research interests span machine learning, mathematical logic, declarative programming, software reliability, artificial intelligence, constraint solving and computational geometry. My work has two strands, one in developing the theoretical foundations of these areas, the other in applying them, particularly in static program analysis using abstract interpretation. Formally reasoning about code using abstract interpretation makes it an important tool for the software engineer interested in verification and security.

Research

Research Interests

My research interests are centred on static program analysis, the development of the techniques used and building tools to apply this. In particular I am interested in applying geometrical and logical techniques to program analysis. I also have interests in logic programming, constraint solving and mathematical logic. Recent projects I have been involved in include the EPSRC project VIP: Verification with Integer Polyhedra.
