Staff profile

About me:

I am an Associate Professor of Statistics at Durham University. Previously, I had academic positions at Imperial College, Manchester and KU Leuven. My research mainly focuses on high dimensional statistics, change point analysis for high dimensional data, longitudinal data analysis, linear and nonlinear mixed models, survival analysis, nonparametric methods, joint modelling and model diagnostics. A major focus of my research has been on developing novel statistical methods and models for the analysis of complex data such as high dimensional data and multilevel/longitudinal data, especially from medical and health research as well as finance and social science.

I serve as Associate Editor for "Statistics & Probability Letters" journal.

I achieved Fellowship of the Higher Education Academy in 2020. This year I am teaching the course "High Dimensional Statistics" for final year maths and statistics students. Last year I taught the MSc course "Models and Methods for Health Data Science". 

If you are interested to do a PhD in Statistics or Data Science, please get in touch.
