I am postdoctoral fellow at Beijing International Center for Mathematical Research, Peking University, supervised by Jian Ding. I obtained my PhD from the Department of Statistics and Operations Research at the University of North Carolina, Chapel Hill, under the supervision of Sayan Banerjee and Mariana Olvera-Cravioto.
Research Interests
I am broadly interested in probability. More specifically, I am interested in random graphs and networks, and process on them. My current work includes describing the local weak limits of various random graph models through couplings, and analyzing local properties like the distribution of degrees and PageRank scores of these models.
