Biography
Z.-Q. Wang graduated in 1982 from Jilin University China majoring in mathematics, and received his MS degree and PhD degree in mathematics from the Chinese Academy of Sciences, in 1984 and 1986, respectively. After post-doctoral training in Peking University and Courant Institute of New York University, and holding visiting positions at University of Utah and University of Wisconsin, he joined Utah State University in 1991 as an assistant professor. He was promoted to associated professor with tenure in 1994 and to full professor in 1998. He served from 1994-1997 as Director of Graduate Studies in Mathematics and Statistics at Utah State University. In 1998 and 2020 he was awarded Researcher of The Year in the College of Sciences at Utah State University. In 2020 he was awarded Utah State University Robins Award - the 2020 Faculty Researcher of the Year. He was elected a Fellow of American Mathematical Society 2015.
