Hi, I'm Jacky Yibo Zhang

I am a PhD student in the Department of Computer Science at University of Illinois at Urbana-Champaign, where I am fortunate to be advised by Sanmi Koyejo. I completed my undergraduate study at the University of Science and Technology of China. I am broadly interested in
  • Machine Learning: broadly in understanding and designing machine learning algorithms, especially from a fundamental perspective.
  • Optimization: non-convex optimization, combinatorial optimization, stochastic optimization, submodular optimization.
  • Algorithms: approximation algorithms, heuristic algorithms.
Other than research, I love photography, music, soccer, etc.
