I am a PhD student at the University of Michigan. My adviser is Seth Pettie. Before coming to Michigan, I was a Master's student at the National Taiwan University, under the supervision of Hsu-Chun YenI have a broad interest in many topics in theoretical computer science. Currently I am mostly interested in the complexity of local distributed graph problems (see my FOCS'16 and FOCS'17 papers). My e-mail: cyijun@umich.edu.
