My research has ranged from field studies of the ecology and evolution of animal behaviour to experimental laboratory studies of the evolution of sex and sexual selection to the computational molecular evolution of HIV-1. I currently focus on the population and evolutionary genetics of adaptation at the molecular level. Using HIV-1 as a model system, I study the interactions between mutation, genetic drift, recombination and natural selection as the virus adapts to its human host. My approach is purely computational and involves the analysis of molecular sequence data and the use and development of analytical and simulation models. Although this work addresses questions about the most fundamental mechanisms of evolutionary change, anything learnt about the virus’s adaptive evolution may be useful in devising strategies for its control.
