ABOUTProf. Dennis K. Lieu was born in San Francisco in 1957. He is a 1974 graduate of Lowell High School. He pursued his higher education at the University of California at Berkeley, where he received his BSME in 1977, MSME in 1978, and D.Eng. in mechanical engineering in 1982. His major field of study was dynamics and control. His graduate work, under the direction of Prof. C.D. Mote, Jr., involved the study skier/ski mechanics and ski binding function. After graduate studies, Dr. Lieu worked as an advisory engineer in the disk file industry with IBM San Jose, where he directed the specification, design, and development of mechanisms and components in the head-disk-assemblies (HDA) of disk files. 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. Berkeley campus. Prof. Lieu is a member of Pi Tau Sigma, Tau Beta Pi, and Phi Beta Kappa. His professional affiliations include ASEE and ASME.INTERESTS Applied research in the mechanics, design and operation of high speed electro-mechanical devices. Emphasis on vibration source control in magnetic circuits, stability of composite structures, and feedback control. Applications include precision spindle-motor assemblies, linear and rotary positioning systems, and robotics. Biomechanics of sports and injury. Design and testing of headgear and chest protectors for sport applications.Teaching at all levels, especially of mechanics, electro-mechanics, machine design, and graphics. Special interest in organizing a curriculum with increasing emphasis on innovation through design projects and case studies. |
