About me

I am an Assistant Professor in the Department of Electrical and Computer Engineering at the University of Rochester. I did my Ph.D. at Rensselaer Polytechnic Institute (RPI), fortunate to be advised by Prof. Tianyi Chen (now at Cornell). I obtained my M.S. in Electrical Engineering from RPI in 2021, and my B.S. from Huazhong University of Science and Technology (HUST) in 2017.

My research lies at the intersection of machine learning, optimization, and statistical signal/image processing, with a current focus on the theory and applications of multi-objective and multi-level optimization and learning. Motivated by real-world scientific and engineering systems, I develop foundations to address problems involving competing objectives, resource constraints, multiple data modalities, heterogeneous users and devices, and hierarchical/multi-criteria decision-making under uncertain environments. I aim to connect theoretical insights with practical needs.

I am always looking for highly motivated students and postdocs. If you are interested, please check out more details here.
