Research Interests

Broadly, our research interests revolve around two related topics: 1. The role of lateral (horizontal) gene transfer in the evolution of microorganisms and 2. The study of host-microbe interactions, with particular focus on the human gut microbiome in health and disease. We are interested in fundamental questions in microbial ecology and evolution: What are the factors that drive or limit gene flow between prokaryotic species? How were the first eukaryotes formed? How does host specificity evolve? Which forces shape the population structure of microbial communities in the mammalian microbiota? Which microbial species can cause chronic diseases?

Microbial ecology in health and disease: The human microbiota has been attracting tremendous interest since there is increasing evidence supporting the involvement of the gut microbiota in several human diseases: from inflammatory bowel diseases, colorectal cancer and irritable bowel syndrome to metabolic syndrome and cardiovascular disease.

Impact of horizontal gene transfer on microbial evolution: Using a variety of bioinformatic approaches we identify laterally transferred genes and study their evolution. We also investigate why some gene functions are transferred frequently while others are only rarely horizontally acquired. We also study barriers to gene transfer, in particular the microbial immune system - CRISPR-Cas.
