I am a fourth year Ph.D. student in the Department of Statistics at University of Wisconsin-Madison, advised by Professor Anru Zhang. Before coming to Madison, I received my bachelor's degree from School of Mathematical Sciences at Zhejiang University in 2017.

My profile at Google Scholar
I am broadly interested in methodology and theory in high-dimensional statistics, machine learning and optimization. My recent interest focuses on challenges in large-scale statistical matrix/tensor inference. These challenges arise as the classic methods suffer from either statistical sub-optimality or computational limitation. In theory, I focus on studying the statistical guarantee for general non-convex optimization methods; in practice, I develop efficient algorithms in applied data science.
