Clare Dixon is a senior lecturer in the Department of Computer Science at the University of Liverpool. She graduated with a first class B.Sc. (Hons) Degree in Mathematics and Management Sciences in 1986 from the University of Hull, an MSc in Systems Design from the University of Manchester in 1992 and a PhD in Computer Science in 1995. She has also worked as a mathematics teacher and a software engineer. From 1995-2000 Dr Dixon worked as a research fellow and then as a research lecturer at Manchester Metropolitan University. She was appointed lecturer in the Department of Computer Science at the University of Liverpool in 2001 and was promoted to senior lecturer in 2004. She is a member of the Logic and Computation Research Group.
Dr Dixon is interested in the specification and verification of systems. Specification involves describing a system using a language with clear and unambiguous semantics. Verification involves showing that properties of that system do, in fact, hold. For specification we use a variety of logical languages, often temporal or modal logics. Temporal logics are useful to describe systems that change over time. Modal logics incorporate possible worlds that can be used to describe knowledge or belief. Probabilities can be incorporated to deal with uncertainty. Verification is used to show that certain properties do hold for some system. In the group we use two main methods for verification--model checking and deduction. The former takes the model of a system and checks that a property specified in some logic holds on that system. Deduction involves the use of mathematical proof. Dr Dixon has been involved with the design, development and application of proof methods for such logics and has applied verification techniques to a range of application areas including robot swarms.
