I obtained my Ph.D. in CS at Stevens Institute of Technology, advised by Professor Jie Shen.
My area of research is on Machine Learning Theory and Algorithmic Robustness. I study scenarios when machine learning algorithms are faced with modern challenges such as malicious adversaries, data deficiency, and unreliable human feedbacks; meanwhile, my interest goes well beyond that, including but not limited to data privacy, algorithmic fairness, and algorithmic game theory. Recently, I have been concerned about multiclass learning problems.
News:
Passed my thesis defense on April 24, 2024! Thanks to all committee members!
Received the Stevens Excellence Doctoral Award.

Research Seminar:
The machine learning theory seminar is paused for now.
Misc:
I enjoy dancing as a hobby, for which I was active in Hong Kong and New York City from 2013 to 2020. It teaches me hard-working is the key to any achievement.
Meanwhile, I play ultimate frisbee to keep myself physically active.
