My name is George Ma (Jiangyan Ma). I am an EECS PhD student at UC Berkeley, advised by Prof. Somayeh Sojoudi. Previously, I was an undergraduate student at Peking University, where I did research on graph learning at Prof. Yisen Wang’s lab. My email: george_ma@berkeley.edu. My CV: George Ma’s CV. I actively write blogs on Zhihu: George M’s Zhihu Homepage.
