I am a geneticist with a primary interest in pathogens and their vectors. My research applies bioinformatics and next-generation sequencing (NGS) techniques to study evolutionary genomics and gene expression in these organisms.

I obtained a degree in genetics from the University of Nottingham (2002), where I became fascinated by parasitology and by population genetics. I combined these themes in my PhD research at the London School of Hygiene and Tropical Medicine (2007) on the population and evolutionary genetics of malaria parasites in response to host immunity. I moved to the University of Liverpool in 2008, where I learned the fundamentals of bioinformatics to analyse NGS data. This I applied in a number of projects including one of the first evolutionary genomic studies of the enteric parasite Entamoeba histolytica, the causative agent of amoebic dysentery, and a transcriptomic analysis of the gene expression landscape of the fungus Aspergillus nidulans, which sparked an interest in gene expression and its regulation. During this time I worked closely with Liverpool’s Centre for Genomic Research (CGR) and was head of the CGR bioinformatics group before moving to the Liverpool School of Tropical Medicine in 2014 to apply NGS analysis to understand the population genomics and genetic mechanisms of insecticide resistance in mosquito vectors of human disease. I joined Liverpool John Moores University in 2018 as a lecturer in Genetics.
