Dr. Chaoqun Liu received his BS in 1968 and MS in 1981 from Tsinghua University, Beijing, China and PhD in 1989 from University of Colorado at Denver, Colorado, USA. He is currently the Distinguished Professor, a highest honored academic title, and Director of Center for Numerical Simulation and Modeling at University of Texas at Arlington, Arlington, Texas, USA. He has worked on high order direct numerical simulation (DNS) and large eddy simulation (LES) for flow transition and turbulence since 1990. As PI, he has been awarded with 50 federal research grants of over 5.7 million US dollars since 1990 in the United States. He has published 10 books, 98 journal papers and 139 conference papers. As a principal lecturer, he held TGS2015 Workshop, New Theory of Turbulence Generation and Sustenance, Tsinghua University, Beijing, China, June 4-6, 2015, sponsored by 20 research institutions with over 220 audiences. He also chaired first and third US AFOSR international conference on DNS/LES in 1997 and 2001. He is a well established expert in high order DNS/LES for flow transition, turbulence, and shock and boundary layer interaction.
