About me

I am a Research Associate in Statistics at the University of Bath. I am interested in using statistics to solve real-world problems, with particular interest in environmental and health applications. My research interests include changepoint analysis, dimension reduction, and Bayesian modelling.

My current research, as part of the Centre of Excellence in Water-Based Early Warning Systems for Health Protection (CWBE), focuses on statistics for wastewater-based epidemiology, in collaboration with colleagues in chemistry, life sciences, psychology and engineering.

I have previously worked on projects including post-selection inference for changepoint detection, and mapping urban deprivation using multiple data sources. More details can be found under the Research tab.
