Tao Ni, Ph.D.

About Me

I'm a Postdoc at the City University of Hong Kong. Before that, I completed my Ph.D. from the City University of Hong Kong, my Master's degree from the Australian National University (ANU), and my Bachelor's degree from Shanghai Jiao Tong University (SJTU).

I am currently refactoring my homepage. More details will be released soon.:)
