Research Interest :

Biological Questions. I am interested in the population genomics of microbial species. The main focus of my lab is the comparative analysis of multiple genomes of the Lyme disease pathogen. The goals of my research include reconstructing the history of worldwide diversification of the Lyme disease bacteria, an understanding of the mechanisms of their genome evolution (e.g., the roles of recombination and natural selection), and inference of gene and genome functions.

My Research Approach is bioinformatics, and more specifically, the computational and statistical testing of evolutionary hypotheses. Students learn and use modern computational tools such as relational database/SQL, Perl/BioPerl, and statistical computing with R.
