I will be a Ph.D. student in Mathematics at University of South Carolina starting from Fall, 2020. I am interested in combinatorics, graph theory, and their applications to theoretical computer science. I studied Mathematics with minor in Computer Science at University of Utah, and graduated in Spring, 2020.

I have been writing blogs since 2009, though I am not as productive as I was before. I have run the Chicago Marathon in 2017 and two half-marathons in Shanghai in 2014 and in Hong Kong in 2016. I also co-led the Chinese translation program for Gamification course on Coursera.
