Wei Biao Wu is a Chinese-born statistician. He is a professor of statistics at the University of Chicago.

Education and career

Wu attended Fudan University, receiving his bachelor's degree in 1997. He went on to the University of Michigan for graduate studies, receiving his PhD in 2001 under the supervision of Michael Woodroofe and Sándor Csörgő. He was hired at the University of Chicago shortly after completing his PhD, and has remained there since.

Wu is best-known for his work on dependence, in which the main new idea is to interpret random processes as physical systems, and to examine coefficients that would have physical meaning.^{[1] [2]} According to Google Scholar, this work has been cited over 350 times.^[3] Wu has written over 100 papers.^{[4] [5]}

Wu has more than 20 students and their descendants working in academia.

In all, he has published 38 papers with ≥38 citations each.

Personal life
