About me

I am currently a Ph.D. student in the University of Illinois Urbana-Champaign (UIUC), advised by Alexander Schwing. Previously, I obtained a MPhil degree from the Hong Kong University of Science and Technology (HKUST), advised by Yu-Wing Tai and Chi-Keung Tang.

I am interested in artificial intelligence and mainly work on computer vision. I believe in AGIs and their ability to transform the human civilization -- such should be our ultimate goal.


“Ho Kei” (with the space) is my first name and “Cheng” is my last name. “Rex” is the commonly used “english name” that is not part of my legal name.
