My name is Z. Sun, a 2nd year PhD student in machine learning and computational statistics at Department of Statistical Science, University College London. I am very very lucky to be supervised by Prof. F-X Briol and Prof. J-H Xue. Before that, I accomplished my M.Sc at University of Oxford. I am an awardee of Cambridge International Scholarship 2019.

Research Interest

In general, I am very interested in computational statistics and machine learning. Recently, I have worked on meta-learning, control variates and Stein’s method.
