The research done in this group is on mathematical population genetics with emphasis on models related to human population genetics. At the present time, the main topics of study are as follows:

• population genetics of human genetic diseases, including linkage disequilibrium mapping, estimation of allele age, testing for natural selection, and modeling founder effects;
   
• analysis of human genetic diversity, with the goal of developing methods for inferring historical patterns of migration and population growth from genetics samples from contemporary populations and from recent fossils,
   
• analysis of strong balancing selection caused by overdominance in fitness and by genetic self-incompatibility systems,
   
• modeling the genetic response to infectious diseases,
   
• and interpreting genetic data from a geographically subdivided population.
