Professor P.K. Yeung joined the aerospace engineering faculty at Georgia Tech in 1992, after a post-doctoral appointment at the Pennsylvania State University. He has held the rank of professor since 2005, and has been a professor of mechanical engineering (by courtesy joint appointment) since 2010. He has held visiting appointments at the Chinese University of Hong Kong (department of physics) and Hong Kong University of Science and Technology (department of mechanical and aerospace engineering). Professor Yeung is a world-class expert in direct numerical simulations of turbulent fluid flow, with a particular interest in intermittency, mixing and dispersion, and in the development of massively parallel computational algorithms which have enabled simulations of the largest size known at the present time. His work has been supported by the National Science Foundation (NSF), the Environmental Protection Agency, the Department of Energy (DOE) Oak Ridge National Laboratory, and several major national supercomputer centers. He has given invited lectures in Germany, India, Israel, and Japan, and has participated in extended research visits in Australia and the United Kingdom. According to the Web of Science his work has been cited nearly 3500 times, with an h-index of 36 as of early 2019. He has been a reviewer for various archival journals and funding agencies. He has served on advisory bodies convened by NSF in the area of advanced cyberinfrastructure. Professor Yeung recently served as chair of the local organizing committee for the 71st Annual Meeting of the Division of Fluid Dynamics of the American Physical Society, in 2018. He has worked with the American Association for the Advancement of Science in offering summer internships for undergraduate students with disabilities.
