About Me

I am a PhD student at the Mathematics for Real-World Systems Centre for Doctoral Training. My research interests include approximating network processes and modelling dynamic networks, particularly in reference to the spread and control of sexually transmitted infections. As well as my research, I coordinate the centre's epidemiology reading group. Outside of mathematics, I have a keen interest in the history and philosophy of science.

Current Research

My PhD focusses on how the topological and temporal structure of sexual networks affects the control of sexually transmitted infections (STIs), in collaboration with Public Health England, and under the supervision of Matt Keeling. Currently, my research is focused on understanding the importance of capturing different aspects of network structure in individuals based epidemic models of heterosexual networks.

As well as my research into STIs I am currently supporting SBIDER's Covid-19 research effort, looking at the effectiveness of social bubbles as part of a lockdown exit strategy in collaboration with researchers at LSHTM and the University of Manchester, as well as contributing to technical reviews of the current research literature.
