Research Interests

My research interests are in health and disease throughout human evolution. My PhD research is focused on parasitic infection in the past and the impact of parasitic infection on humans as well as the impact of humans on the spread and evolution of parasites. This research uses techniques including light microscopy and biomolecular identification of parasites from archaeological samples, particularly in the Roman Empire. I have also been involved with excavations of the rural Roman cemetery on the Imperial Estate at Vagnari, Italy since 2011.
