About me
I am a second year PhD student in the Department of Computer Science at the University of Texas at Austin.
I am fortunate to be advised by Prof. Sujay Sanghavi.
I also worked with Prof. Qiang Liu during my first year at UT.
My research focus on the theoritical aspects of machine learning, including but not restricted to optimization, statistics and online learning.
Before moving to Austin, I received the B.S. degree in Fundamental Science and Double B.S. degree in Mathematics and Applied Mathematics from Tsinghua University in 2018. During the undergraduate study, I was fortunate to work with Prof. Jun Zhu on different topics in Machine Learning.
See my CV for detailed information.
