Background:

1980-1984 Ph.D. Degree in Theoretical Condensed State Physics, University of Sussex, UK

1977-1980 B.Sc. Degree in Physics, University College London, UK

 

Research:

I am interested in fundamental questions in biology, with the aim of understanding and explaining

some of the complex phenomena exhibited by populations of living organisms. In my research I

develop and analyse mathematical models to answer questions in evolution, population genetics

and related subjects. This involves the use of mathematics, statistics and computer simulations and

may be described as theoretical biology, mathematical biology or computational biology. Most of

the biological systems I consider have random or stochastic aspects.

 

My current research covers:

Theoretical population genetics and evolution.
I am interested in the way different evolutionary processes, such as mutations with pleiotropic effects, can affect the distribution of continuously varying (i.e., quantitative) traits such as height or weight. Previous work I have coauthored with Joel Peck has established that standard theoretical models, with pleiotropic mutations, can have singular distributions. Work is proceeding on this with Sebastien Gourbiere, Guillaume Martin and Sylvain Gandon.

Random genetic drift.
I am investigating the stochastic processes that occur in populations of relatively small size. I have been involved with analysis of the diffusion equation of random genetic drif and I have recently investigated some of the implications of demographic and selective changes on the probability of fixation. This work is now being extended to more complex problems.

Animal movement.
This work involves establishing statistical tests, performing statistical analyses of data and mathematically modelling the movement and foraging behaviour of Pharaoh's ants. It is being carried out with Pierre Nouvellet and Jonathan Bacon.
