My research

I would describe myself as an evolutionary epidemiologist, with a particular interest in chronic viral infections such as HIV and Hepatitis C. The key aim of my research is to disentangle the often conflicting selection pressures that occur at the, within, and among-host scales, and how this impacts the evolution of these viruses in the face of different intervention strategies such as 'Treatment as Prevention'. To do this I use a range of methods including mathematical modelling, stochastic simulations, and the analysis of deep-sequencing data.

My journey

I have taken a slightly circuitous career path, including an eight-year break from research, during which I completed a Masters, was the Editor of TREE, and had two delightful children. A Wellcome Trust Re-Entry Fellowship enabled me to get back into research after my second year of maternity leave, and since then I have not looked back. I particularly appreciate the flexibility that research gives me – I worked part-time for four years, and often work from home – which is vital since I have a long daily commute and, being a teacher, my partner’s hours are anything but flexible.
