Zihan Feng

I am currently a Ph.D. student at HKUST(GZ), where I am fortunate to be advised by Prof. Jeffrey Xu Yu. Previously, I worked as a Research Assistant at Hong Kong Baptist University, where I was advised by Prof. Xin Huang. I received both my B.Eng. and M.Eng. degrees from Tianjin University, under the supervision of Prof. Yajun Yang.
