Research Interests

Chris Winkler is Research Scientist Emeritus of UMTRI's Engineering Systems Group. He first joined the UMTRI staff in 1969. His research interests include measuring, predicting, and analyzing the handling, braking, and roll-related behavior of pneumatic-tired motor vehicles and their components with a strong emphasis on large, commercial highway vehicles. 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 on the test track and in the field. He has participated in the development and use of sophisticated computer programs simulating dynamic vehicle behavior.

Hobbies and Interests

Chris Winkkler is a private pilot with instrument rating and over 2000 hours as PIC. Much of his spare time is taken up with the care and maintenance of his 1965 Piper Cherokee airplane and his 1965 Porsche 356C. He and his wife, Noel, have enjoyed forty-some consecutive years of attendance at the Stratford Shakespeare Festival. They both enjoy boating and water sports, long vigorous walks, and the fall colors.
