About
I am currently a Ph.D. student in Computer Science and Engineering at University of Michigan. I work on lattice problems with Chris Peikert.
I got my Master's degree in computer science at Courant Institute of Mathematical Sciences, New York University. During that time I worked on lattice problems with Oded Regev, and applied cryptography with Yevgeniy Dodis.
Prior to NYU, I got my Bachelor's degree in computer science at Peking University. My undergraduate research focused on physically unclonable functions, supervised by Yongzhi Cao [zh].
Research Interests
My research interests include the area of lattice problems, post-quantum as well as applied cryptography, theoretical machine learning, and theoretical computer science in general.
