Since November 2018, I am a Senior Lecturer in Statistics at Manchester Metropolitan University. Previously, I was a Research Associate in Statistics at Imperial College London from October 2015 to October 2018. Prior to that, I was a Postdoctoral Fellow in Statistics at KU Leuven, Belgium, from October 2013 to September 2015.
My main research interests are statistical modelling and statistical inference, as well as big data and data science. My research particularly focuses on high dimensional statistics, mixed-effects models, multilevel 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 for the analysis of complex data such as high dimensional data and longitudinal/multilevel data, especially from medical studies.
I teach the undegraduate module "Applied Regression and Multivariate Analysis", and the MSc module "Computational Statistics and Visualisation" for the MSc in Data Analytics. I am also unit leader for the module "Foundation Data Analysis".
