Research Interests

My research is concerned with understanding the way bacterial pathogens evolve, spread and cause disease. I have analysed both epidemiological and genomic data from a wide range of bacteria. A key aim is to develop new bioinformatics and statistical methods that can handle the very large amounts of data made available by novel high-throughput sequencing techniques.

Because of the interdisciplinary nature of my work, I have broad interests in a variety of subjects, including theoretical topics such as mathematical population genetics, Bayesian statistics or Monte-Carlo methods, and biological topics such as bacterial evolutionary processes or pathogen epidemiology.

I have worked on a wide range of bacterial pathogens, especially those causing healthcare associated infections (eg Clostridium difficile and Staphylococcus aureus ) and gastrointestinal infections (eg Salmonella enterica, Bacillus cereus, Campylobacter jejuni and Helicobacter pylori).

I share my time equally between the School of Life Sciences and the Department of Statistics. I am also a member of the Zeeman Institute for Systems Biology & Infectious Disease Epidemiology Research (SBIDER).

I lead the recently created Health Protection Research Unit in Genomics and Enabling Data which is funded by the National Institute for Health Research (NIHR). This project is a collaboration between the University of Warwick, Public Health England, the Centre for Genomic Pathogen Surveillance and the University of Cambridge. Our aim is to provide the methodological backbone required to improve national public health using large scale genomic and epidemiological data.
