I'm interested in the evolution of microorganisms that live on and within the human body (microbiome).

Using ancient DNA, we can investigate how cultural changes, dietary shifts, and disease shaped the human microbiome.

We are also able to understand bacterial evolution in real time, monitoring how pathogens evolved through the course of human history.

Further, we can investigate how the evolution of these microorganisms effects today's diseases and how they may have changed human evolution.
