Advisor: Professor Yao Xie

My research interest lies in statistics and optimization, with a primary focus on sequential change-point detection and their applications in sensor networks and industrial quality control.

I am very fortunate to collaborate with Professors George V. Moustakides, Professor Rui Gao, Professor Huan Xu, Professor Fan-Chi Lin, and Professor WenZhan Song.

Reading Group

Prof. Yao Xie and myself are co-organizing a reading group about Sequential Analysis and Statistical Methods for Machine Learning. Let us know if you are interested in attending and presenting.
