My research concentrates on stellar structure and evolution; because many areas of astronomy are influenced by stellar evolution theory, this has led me to investigate a range of subjects. I am particularly interested in physical processes, such as microscopic diffusion and mixing induced by stellar rotation, which are neglected in standard stellar models and can strongly alter some of the predictions of stellar evolution theory. Current research interests include solar models and the solar neutrino problem; stellar populations; cosmology (big bang nucleosynthesis, ages of globular clusters); angular momentum evolution in stars; and mixing in red giant branch stars.
