Jeongbin John Kim (born 1947) is the Rockwell International Distinguished Professor of mechanical and aerospace engineering in the UCLA Henry Samueli School of Engineering and Applied Science, since 1993.
His primary research interest is numerical simulation of transitional and turbulent flows, physics and control of turbulent flows, and numerical algorithms for computational science.
Kim has been a pioneer in developing direct numerical simulation (DNS) and large eddy simulation (LES) as a reliable and respected tool for studying physics of turbulence.
John Kim received the NASA Exceptional Scientific Achievement Medal in 1985, H. Julian Allen Award from NASA Ames Research Center in 1994, Otto Laporte Award from the American Physical Society in 2001, Ho-Am Prize in Engineering from the Ho-Am Foundation in 2002, and Distinguished Alumni Award from Seoul National University College of Engineering in 2009.
In 2009, Kim was elected a member of the National Academy of Engineering for the development of direct numerical simulation and seminal contributions to the understanding of the physics and control of turbulent flows.
