Yumeng Zhang

I am a Ph.D. student in the Department of Statistics, University of California, Berkeley, advised by Allan Sly. Before coming to Berkeley I got my bachelor degree in Mathematics from Yuanpei College, Peking University.

I am broadly interested in probability theory and its applications. In particular I have recently been working on problems in broadcasting models on trees, random constraints satisfaction problem, Markov chain mixing time and stochastic block model.
