I am a PhD student (since 2015) in the Department of Computer Science at Tsinghua University, advised by Jun Zhu. My research interests are in the area of probabilistic methods and approximate inference. I have worked on topics including variational inference, Gaussian processes, kernel/spectral methods, generative models, and Bayesian neural networks.

Last year I spent the summer at DeepMind, London as a research scientist intern and the rest of the year visiting Vector Institute. I have also spent a summer interning at RIKEN-AIP, Tokyo. In 2018, I was awarded the Microsoft Research Asia Fellowship. I received my B.E. from the Department of Computer Science and Technology at Tsinghua University.
