Population samples of DNA sequences contain information about both contemporary and ancient processes and events. I use mathematical models to describe how these current and historical factors conspire to produce the patterns of genetic variation which are readily observable among individuals within species. I employ both analytical and computational techniques to make inferences about these factors from patterns of genetic variation. 

The field I work in is called Theoretical Population Genetics. Follow the publications link on the left for a list of references and articles to download for your fair use. These articles cover a number of topics, mainly in the sub-field called Coalescent Theory in which the objects of study are patterns of ancestral genetic relationships, or gene genealogies. You will find a bunch of articles about the genetics of subdivided populations with restricted migration, but also others about populations in which one or a few individuals can have very large numbers of offspring, and about a problem that has been overlooked in Coalescent Theory: that all loci in the genome have been transmitted through a single population pedigree. I sincerely hope you enjoy reading these. If you have any questions, please get in touch with me by email at the address below.
