TECHNICAL BACKGROUND AND PROFESSIONAL CAREER

After receiving his Ph.D. degree in Mechanical Engineering from UC Berkeley in 1988, he worked in the private sector before returning to Berkeley in 1994.  Prior to joining PATH, Dr. Chan worked in the field of vehicular passive safety systems. While being involved in the research, and development of crash sensing technologies, he also gained first-hand knowledge on general passive restraint systems, as he worked with automotive tier-one supplies and automotive OEMs. During 1990-1994, he worked in litigation support on accident reconstruction and participated in numerous cases of vehicle crashes, through which he gained insights on the interaction of drivers, vehicle characteristics, roadway environment, and their impacts on driving risks.

Due to his nationally recognized expertise in crash sensing and vehicular safety, Dr. Chan was invited by Society of Automotive Engineers (SAE) to provide tutorials to more than 500 automotive professionals in an SAE seminar series. He has given lectures to various organizations. He collaborated with SAE to publish a book and a video tutorial, and he was the recipient of the 1998 SAE Forest R. MacFarland Award for his outstanding contributions to engineering education. 

Dr. Chan was also significantly involved in the research and development of vehicle automation technologies. During the years of the National Automated Highway Systems Consortium in 1990s, he represented PATH in the national working group of technology development and evaluation.  Subsequently, he also worked in projects that involved the use of various technologies for vehicular automation systems.  In 2003, he led a team of researchers and engineers in the Demonstration of Bus Automation Technology in San Diego.  The project subsequently won the prestigious award of the Best of ITS Research Award from the ITS America in 2004.

Dr. Chan also collaborated with industrial and academic partners in developing and implementing communication-enabled cooperative systems in multiple projects. Applications include vehicle-to-vehicle and vehicle-to-infrastructure, vehicle-to-pedestrian, and road equipment-to-network operation scenarios. These projects were supported by and jointly conducted with federal and state governments, automaker consortium, and private-sector partners.

Dr. Chan served as a visiting Professor at the University of Tokyo, Institute of Industrial Science from May 2006 to January 2007 and a visiting scholar at Institute of French National Transport Research (INRETS, which is now IFSTTAR) in the summer of 2004.
