Assistant Professor in Statistics in the Department of Mathematical Sciences

(email at reza.drikvandi@durham.ac.uk)

About me:

I am an Assistant Professor of Statistics at Durham University. My research mainly focuses on high dimensional statistics, longitudinal data analysis, mixed-effects models, nonparametric and semiparametric models, joint modelling, model diagnostics and missing data problems. 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 longitudinal/multilevel data, especially from medical and health studies.

I have achieved Fellowship of the Higher Education Academy. I currently teach the course "Topics in Statistics III/IV" for final year mathematics students.
