Professor J.-Y. Chen has near thirty years of experience on research of combustion processes after Ph.D. degree and two years of practical engineering with Boeing aircraft company. His research topics include air pollution, supersonic combustion, reduced reaction mechanisms, soot formation, flame extinction and re-ignition, applications of catalysts to combustion processes. Professor Chen earned his Ph.D. degree from Cornell University in 1985 with his thesis research on modeling of turbulent reacting flows. Since then, he has worked at Sandia National Laboratories Combustion Research Facility at Livermore as a senior scientist staff member for six years. During this period, he continued and expanded his numerical modeling work in many areas of turbulent reacting flows. This research included development of realistic chemical kinetics for Probability Density Function (PDF) methods, reduced reaction mechanisms, turbulent mixing models, and models for interactions between turbulence and chemical kinetics. These model developments have been applied to studies of combustion in supersonic flows, soot formation in turbulent flows, flame extinction and re-ignition, and NOx formation in turbulent flames. Many of these topics are related to gas turbine combustion. Professor Chen joined the faculty of Mechanical Engineering Department of University of California, Berkeley, in the Fall of 1991. His current research focuses on combustion-generated pollutants in laminar and turbulent flames, catalyst combustion, multi-component droplet combustion, homogeneous charge ignition and GDI engines, and large eddy simulations of turbulent flows, reduced chemistry for transportation fuels, and microwave assisted combustion. Professor Chen has coauthored one textbook of combustion and some one hundred and twenty-four journal reviewed papers of various topics in combustion and fluid mechanics.

Professor Johnson’s research can be broadly categorized as materials characterization at the intersection of mechanical engineering and materials science. The thrust of his effort is to under-stand macroscopic material behavior in terms of its microstructure and to develop material models that accurately capture the response of a wide range of materials. His recent work falls into four areas: 1) microscopic modeling of failure modes in brittle materials, 2) understanding the failure of materials under impact loading, 3) developing macroscopic material models for the large-deformation response of metals, and 4) application of X-ray tomography with micron-level resolution to visualize the growth of damage in structural materials. Professor Johnson is also currently the Chair of the Board on Admissions and Relations with Schools (BOARS), a committee of the systemwide Academic Senate for the University of California.

He directed the design and control of high performance DC brushless motors and control of spindle and structural vibration in the IBM 3390 disk file. In 1988, Dr. Lieu joined the Mechanical Engineering faculty at UC Berkeley. His interests include applied research in the mechanics of high speed electro-mechanical devices, and the mechanics of magnetically, electro-magnetically, and eddy current generated acoustic noise and vibration. He currently supervises approximately 6 graduate students in the Electro-mechanical Design Laboratory in 2163 Etcheverry Hall. At the University, Prof. Lieu teaches courses in Engineering Graphics and Design of Electro-mechanical Devices. He also leads a special seminar class in the design of protective equipment for sports.

 

Prof. Lieu holds a 3rd degree black belt in taekwondo, and is a martial arts instructor at UC Berkeley. His interest in biomechanics and sport equipment design has led to many seminars and papers on these topics. Prof. Lieu was the recipient of a National Science Foundation Presidential Young Investigator Award in 1989, the Pi Tau Sigma Award for Excellence in Teaching in 1990, and the 1992 Berkeley Distinguished Teaching Award, which is the highest honor for teaching excellence on the U.C.
