My research is in verification: formal techniques for checking that systems function correctly. In particular, I work on quantitative verification, which is used to check quantitative properties such as safety, reliability, performance and many others. See here for a short introduction to the topic.

This involves building and analysing models with probabilistic and real-time behaviour. I work on novel techniques to improve the scalability of verification (e.g. abstraction, compositionality), game-theoretic verification methods, and applications of these techniques to a variety of areas, including robotics, computer security, systems biology and DNA computing.
