About Me

I recently completed my master degree in computer science at the University of Waterloo under the supervision of Prof. Yaoliang Yu. I wrote my thesis on optimization algorithms for Wasserstein adversarial robustness. Previously, I did my undergraduate in computer science at Nanjing University.

My research is in machine learning and optimization. I am interested in developing efficient and robust learning algorithms. In particular, I am interested in large-scale optimization, adversarial robustness, generative models.
