Guangxuan Xiao   肖光烜

I am a second-year Ph.D. student at MIT EECS, advised by Prof. Song Han. I graduated from the Department of Computer Science and Technology at Tsinghua University in 2022, advised by Prof. Zhiyuan Liu. I have been very fortunate to work with Prof. Jure Leskovec as a summer intern in 2020, with Prof. Jiajun Wu and Prof. Leslie Pack Kaelbling through the Stanford UGVR Program.

I love to play soccer. I was the captain and striker of my department soccer team.
I also love to play table tennis, Go (Weiqi), and piano. Beethoven's works are my favorite.
