I am a Lecturer in Statistics at the School of Mathematics since September 2013.   Before that I was an Assistant Professor at the Department of Mathematics at Michigan Technological University (2010-2013) and a New Researcher Fellow at the Statistics and Applied Mathematics Sciences Institute (SAMSI - North Carolina, US).  My research has been funded by National Science Foundation, the London Mathematical Society, the GW4 Network and the Welcomme Trust. 

My research interest includes high-dimensional statistics, supervised and unsupervised dimension reduction, computationa statistics, machine learning and text data analysis.   I am happy to discuss with prosepctive Ph.D. students any research projects they are interested with if they want to work with me.
