Biography

I am a M.S. student in the Department of Computer Science & Engineering at the University of Minnesota, Twin Cities, also work as a graduate research assistant in Prof. Ju Sun’s group.

Broadly, my research is about optimization for machine and deep learning, robustness in vision recognition and AI for science and engineering. Specifically, I am interested in: 1). User-friendly and scalable software for constrained optimization in deep learning; 2). Adversarial robustness in computer vision; 3). AI for topology optimization; 4). Learning from unbalanced biomedical data.

Prior to this, I obtained my first M.S. degree in Materials Science at the University of Minnesota, Twin Cities, and my B.S. degree from the School of Physics, Nanjing University. Before joining Prof. Ju Sun’s group, I worked as a research assistant in Prof. J. Ilja Siepmann’s computational chemistry group.
