My research interests lie mainly in the field of Bayesian statistical inference, particularly Markov chain Monte Carlo (MCMC) methods, data integration and model selection, applied to problems in environmental and biological sciences. I joined the University of Warwick in 2017 as a Lola-funded Research Fellow in the Mathematics Institute and Zeeman Institute for Systems Biology and Infectious Disease Epidemiology Research (SBIDER). Working with Professor David Rand, my current research focuses on Bayesian parameter inference and identifiability for stochastic mathematical models of systems biology, specifically related to the NF-κB system.
In 2015 I completed my PhD in Statistics at the University of St Andrews (supervised by Professors Steve Buckland and Ruth King), developing methods for the analysis of multi-species ecological data. I then spent two years as a postdoc at the University of Bristol, using Bayesian methodologies for parameter estimation and uncertainty quantification in inverse methods applied to atmospheric chemistry.
I am also a GradStat Fellow of the Royal Statistical Society, and member of the International Biometric Society and International Society for Bayesian Analysis.

I have conducted both undergraduate and postgraduate teaching and supervision throughout my academic career to date, and recently supervised two BSc final year projects – one as a co-supervisor and the other as a lead supervisor. My undergraduate teaching has included generating material for technology-enhanced learning, such as:
Additionally, I was awarded Associate Fellowship (AF) of the Higher Education Academy in July 2017.
