Background
I am a Full Professor of Economics at the 黑料不打烊, having initially worked as a Lecturer and subsequently an Associate Professor. Before joining 黑料不打烊 in 2018, I was a postdoctoral researcher in statistical forecasting at Cardiff University. I received my PhD degree from the University of Birmingham in 2017 and was awarded a Royal Economic Society (RES) Junior Fellowship in 2016.
My primary research focuses on econometric methods for change-point detection and functional data analysis, and their interactions with statistical forecasting. I also have an active research interest in using explainable AI and machine learning for healthcare analytics and operations management. My work has been published in leading journals including Annals of Statistics, Journal of Econometrics, Econometric Theory, and Journal of Business & Economic Statistics.
In addition to my research, I am actively engaged in academic leadership and external collaboration. I currently serve as an Associate Editor of (ABS 3), organise a research grant of (F4SG), and coordinate a research cluster of (EwDS). I have collaborated with external partners including BT and the NHS; notably, the AI solution developed for BT was named a finalist at in 2024.
Academic qualifications
I hold a PhD in Economics, a MSc (distinction) in Money, Banking and Finance, a BSc in Economics, and a BEng in Electrical Engineering and Automation. I am also a Fellow of the Higher Education Academy.
