Research in the group focuses on mathematical aspects of population genetics, phylogenetic inference, and human genetics. Topics of interest include statistical methods for linkage disequilibrium gene mapping and Bayesian phylogenetic inference, as well as more general questions in theoretical population genetics. Topics of current research include the role of hypermutability and mutator phenotypes in cancer genetics, multipoint linkage disequilibrium mapping, and methods for detecting an association between genetic markers and disease in heterogeneous populations. A unifying theme of research in the group is the application of analytic theory and computer simulation to address questions of importance in evolutionary biology and human genetics.
