My name is Z. Sun, a 3rd year PhD student in machine learning and computational statistics at Department of Statistical Science, UCL. I am very very lucky to be supervised by Prof. F-X Briol and Prof. J-H Xue.

Research Interest

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