Parviz Moin is the Franklin P. and Caroline M. Johnson Professor in the School of Engineering and founding director of the Center for Turbulence Research at Stanford University. He pioneered the development of Direct and Large Eddy Simulation techniques and their use for the study of turbulence physics, control and modeling concepts. Professor Moin is a member of the US National Academy of Sciences and the National Academy of Engineering, and is a Fellow of the American Academy of Arts and Sciences, the American Institute of Aeronautics and Astronautics (AIAA), and the American Physical Society (APS). Ronald Chan is a Senior Scientist at the Institute of High Performance Computing (IHPC) of the Agency for Science, Technology and Research (A*STAR) in Singapore. He received his S.B. in Engineering from the Massachusetts Institute of Technology and conducted his Ph.D. research, with the support of A*STAR's National Science Scholarship, on the turbulent bubble breakup cascade in oceanic breaking waves at the Center for Turbulence Research at Stanford University, where he assisted in the instruction of the graduate turbulence course that inspired this book. His research interests focus on simulating and modeling multiphysics turbulent flows and plasmas.
