Profile

I joined the health Economics and Decision Science (HEDS) Group as a Research Assistant in 2014. My background is in economics.

I previously worked at HM Treasury in the International Finance Directorate and completed my MSc and PhD in Economics at the University of Sheffield. My PhD thesis investigated the relationships between globalisation, productivity, knowledge and firm structure using UK firm-level data. This provided a strong grounding in micro-econometrics and quantitative analysis. I also have experience of teaching and lecturing in Economics and Statistics and assisting with STATA workshops.

My main role in ScHARR is to participate in a project to analyse and employ statistical methods for adjusting survival estimates on datasets that are confounded by treatment crossover.
