Research summary

I work on problems at the boundary of probability theory and information theory.

I am interested in the relationship between properties of entropy and limit theorems, such as the Central Limit Theorem and Law of Small Numbers (Poisson convergence). This includes trying to understand relationships between information-theoretic properties such as the Entropy Power Inequality and maximum entropy theorems and probabilistic ideas such as log-Sobolev inequalities and transportation of measure. I have a particular interest in developing discrete analogues of these results.

I also work on more applied problems relating to communications. I have a particular interest in characterizing `best possible ...

Biography

I am Professor of Information Theory, and a member of the Institute for Probability, Analysis and Dynamics and the Institute for Statistical Science. I moved to Bristol in 2006, having been previously Max Newman Fellow of Cambridge University and Clayton Research Fellow of Christ's College Cambridge.

I gained a PhD from the Statistical Laboratory in 1999 (my supervisor was Yuri Suhov, the title was Entropy and Limit Theorems), having been an undergraduate at Queens' College Cambridge.
