Research Interests

I apply ecological and evolutionary theory to better predict the evolutionary dynamics of infectious disease in humans and other species, with the ultimate aim of informing public health decisions.  In particular, I am interested in disentangling the, often conflicting, selection pressures acting on pathogens at different ecological levels, and to assess the impact this has on the evolutionary epidemiology of infectious disease.  My approach is inter-disciplinary in nature, including the application and development of evolutionary theory, using and making sense of next generation sequence data, and applying epidemiological theory. The current focus of my research is on HIV and Hepatitis C, but the theory I develop has implications for our understanding of infectious disease more widely.
