My research interests are to improve our understanding and control of the spread of infectious diseases through the analysis of a wide range of data using statistical methods and mathematical models.

I joined the Vaccine Epidemiology Research Group at Imperial College London in March 2014.

My current research mainly focuses on the epidemiology of enteroviruses. My primary interest is to identify the epidemiological and evolutionary determinants of the epidemic patterns of non-polio enteroviruses. This project is in collaboration with Prof Nicholas Grassly (Imperial College), Prof Bryan Grenfell (Princeton University), and colleagues at the University of Liverpool, Public Health England (PHE) and the US Centers for Diseases Control and Prevention (CDC). Together with colleagues at Imperial College and CDC we are also investigating the emergence and spread of vaccine-derived polioviruses (VDPVs). The main goal of this work is to inform decisions by the Global Polio Eradication Initiative concerning the global withdrawal of the oral poliovirus vaccine. More generally, I am also interested in the ecological and evolutionary effects of vaccination, and their impact on the efficacy and effectiveness of vaccines.

I completed my PhD in December 2013 in the Pharmacoepidemiology and Infectious Diseases Unit, at Institut Pasteur in Paris.
