Chris Winkler has been involved in the management and conduct of research concerned with the measurement, analysis, and prediction of the dynamic behavior of motor vehicles and their components for forty years. He has been responsible for the design and construction of a variety of laboratory and field devices for measuring the properties of vehicles and their components. He has been responsible for full-scale vehicle testing programs at the test track and in the field. He has participated in the development and use of sophisticated computer programs simulating dynamic vehicle behavior. Mr. Winkler has served in capacities ranging from Project Director to Principal Investigator to Staff Engineer. He has been involved in all aspects of research projects from initial conception and preparation of proposals through to the writing of final technical reports. More recently, he designed and led the fabrication of a very high precision road profiler.

Winkler has lectured on the subject of heavy vehicle dynamics at the University of Michigan, Cambridge University (UK), the Open University (UK), University of Queensland (Australia), Tsinghua University (Beijing, PRC), and Xian Highway Institute (Xian, PRC), and privately at the request of Navistar Corp., PACAR Corp., Freightliner Corp., Eaton Corp., Saab-Scania AB (Sweden), Transport Canada, the University of Saskatchewan, and CSIR/WITS Univ. South Africa.

Winkler has served as a special engineering consultant to the Administrator of the National Highway Traffic Safety Administration of the U.S. Department of Transportation, to the U.S. Department of Justice, the U.S. Navy, the Michigan Department of Transportation, Transport Canada, the National Research Council of Canada, and the transportation agencies of the provinces of Saskatchewan and New Brunswick, Canada.
