This is the third issue of the Journal of Mechanical Design to be printed since Prof. Lung-Wen Tsai, my predecessor, died suddenly just after Thanksgiving last year, and it contains the last of the papers that were accepted for publication under his supervision. Prof. Bahram Ravani prepared the enclosed memorial together with a list of Prof. Tsai’s published works. A more complete list is available at the ASME Design Engineering Division website:

I vividly recall the ASME Mechanisms Conference over two decades ago, when Prof. Tsai introduced himself and took me to lunch, beginning regular interactions that I found inspiring. The shear pleasure that Prof. Tsai took in all of his activities was contagious and energizing. It was clear from the presentations at his memorial that professors, classmates, friends and family treasured the warmth of his personality and the energy of his enthusiasm.

This issue also marks a transition in Associate Editors. I would like to recognize the following Associate Editors of the Journal of Mechanical Design, who have served our community with distinction, and have now completed their terms:

Prof. Choi received his B.S. degree from Yonsei University, Korea (1970) and M.S. and Ph.D. degrees from the University of Iowa (1977, 1980) where he is currently a professor in the department of mechanical engineering and industrial engineering. He is a Fellow of ASME, an Associate Fellow of AIAA, an Executive Committee member of the International Society for Structural and Multidisciplinary Optimization (ISSMO), and an associate editor of three journals. Areas of interest include mechanical system design sensitivity analysis and optimization, reliability-based design optimization, computational methods in mechanics, and integration of CAE tools for concurrent engineering. Dr. Choi is the author/co-author of 214 technical papers and three books.

David B. Dooner

Dr. Dooner received his Ph.D. from the University of Florida in 1991. He was a visiting scientist with the Academy of Sciences in Moscow in 1992 and joined the University of Puerto Rico, Mayagu¨ez, in 1994 where he is currently associate professor of mechanical engineering and teaches kinematics, machine design, computer aided design, and capstone design. His research interests include kinematics, modeling of mechanical systems, along with CAD/CAM of direct contact mechanisms (gear pairs, cam systems). Dr. Dooner’s publications include a text, patents, software, as well as journal and conference publications.

Qiaode Jeffrey Ge

Prof. Ge received his Ph.D. degree in mechanical engineering from the University of California, Irvine, in 1990. He is currently an associate professor of mechanical engineering at the State University of New York at Stony Brook. His research interests include mechanisms and robotics, computational kinematic geometry, CAD/CAM, and application of VR technologies in design and manufacturing.

David O. Kazmer

David O. Kazmer, P.E., is a graduate of Cornell University (B.S., 1989) and Stanford University (Ph.D., 1995). He is currently an associate professor with the department of plastics engineering at the University of Massachusetts, Lowell, where he conducts design and manufacturing research pertaining to net shaped products, and plastics in particular. His research and teaching spans design of products, production machinery, instrumentation, and control systems through start-up and performance measurement. Dr. Kazmer received the 1998 National Science Foundation CAREER Award, the 1998 Young Investigator Award from the Office of Naval Research, and the 2000 University of Massachusetts Outstanding Engineering Junior Faculty Award.
