James Walker

James Walker, Jr. is currently a Principal Engineer specializing in motor vehicle crash reconstruction and chassis, brake, and electronic brake control systems at Carr Engineering, Inc. His prior professional experience includes vehicle dynamics and brake control system development, design, release, and application engineering at Kelsey-Hayes, Saturn Corporation, General Motors, Bosch, Ford Motor Company, and Delphi.
Mr. Walker created scR motorsports consulting in 1997, and subsequently competed in seven years of SCCA Club Racing in the Showroom Stock and Improved Touring categories. Through scR motorsports, he has been actively serving as an industry advisor to Kettering University in the fields of brake system design and brake control systems. Since 2001, he has served as a brake control system consultant for StopTech, a manufacturer of high-performance racing brake systems.

In addition to providing freelance material to multiple automotive publications focusing on chassis and brake technology, Mr. Walker is the author of High-Performance Brake Systems: Design, Selection, and Installation. In 2005, he was presented with the SAE Forest R. McFarland Award for distinction in professional development and education, and in 2010 was designated as an SAE Master Instructor. He obtained his B.S.M.E. in 1994 from GMI Engineering & Management Institute


Driving Instructors 

Ed Bedner is a senior principal engineer with 30 years of experience in the field of vehicle dynamics control systems.  His professional experiences include the design and application of active safety systems, including brake controls, steering controls, driver assistance and autonomous systems at General Motors, Delphi, Autoliv, and Zenuity.Mr. Bedner has been responsible for the development of algorithms related to the estimation and control of vehicle motion, such as electronic stability control, rollover prevention, adaptive cruise control, and lane-tracking functions.  He holds 14 patents and is the author of 3 technical publications. Ed has extensive experience in vehicle handling test methods and instrumentation.  In cooperative projects, he supported NHTSA’s development of tests for rollover propensity and for yaw stability, which led to the NCAP star ratings and FMVSS126.  More recently he has tested and verified systems for driver assistance for customer applications.  He is a certified driver at proving grounds and at winter test sites.Mr. Bedner holds bachelor’s and master’s degrees in engineering.  He has been a co-instructor for SAE’s Applied Vehicle Dynamics course for 13 years.

Patrick Caherty is a Technical Specialist with 25 years of experience in all aspects of on-road vehicle braking systems.  His professional experiences include application and vehicle-level performance development and verification of electronic brake controls, foundation brakes, and friction materials for a number of global suppliers and vehicle manufacturers. Mr. Caherty earned his BSME and competed in Formula SAE at the University of Maryland, College Park.   He has been a co-instructor for the SAE Applied Vehicle Dynamics and Applied Brake Controls seminars since 2006.

Deric Frisch
Deric Frisch has worked in the automotive industry for 30 years and holds degrees in Automotive Engineering and Engineering Technology from MCC and Lawrence Technological University. In 1996-1997 he led the Monroe Community College Formula SAE design team with a focus on frame and suspension design. He has been involved with various vehicle development projects while working at Roush Technologies and Faurecia.

Deric has been involved with motorsports since 1991 and has competed in various events around the U.S. with the SCCA and World Karting Association. Since 1993 he has been a performance driving instructor with the SCCA and several automotive manufacturers. He has also been a voluntary instructor for A World in Motion (SAE Foundation program) within the Detroit city school system which focuses on STEM principals related to vehicle design. In 2017 he was appointed as an Ambassador for the BMW Car Club of America Foundation with a concentration on further developing the Street Survival teen driving program. He has been a co-instructor for the SAE Applied Vehicle Dynamics seminars since 2018.

Erik Maassen is the Test Lab Supervisor for Automatic Transmissions at ZF North America, Inc. in Northville, Michigan.  Prior to this assignment, Mr. Maassen was a Vehicle Dynamics Engineer working at FIAT Chrysler Automotive LLC supporting new and carry-over vehicle programs for all vehicle dynamics attributes for 5-1/2 years.  His work relied on subjective and objective assessment of vehicle response to road and driver inputs to evaluate proposed components and alignments in a variety of conditions.  Objective assessments required Mr. Maassen to select and apply appropriate instrumentation in order to collect and evaluate data.

Mr. Maassen is also an instructor for the BMW Car Club of America since 2001 providing guidance to High Performance Driver Education students at racetracks around the Midwest. He uses his high performance driving experience to teach students the most efficient and safe path around a racetrack helping them to use the maximum capability of their car and to improve their own skills at the limit of adhesion.  In addition, Mr. Maassen invests his driving and engineering experience coaching young drivers through the StreetSurvivial teen car control driving course. With 25 years of Automotive Engineering experience, Mr. Maassen has been enthusiastically supporting the SAE Applied Vehicle Dynamics course since 2006.  His prior professional experience includes application engineering of wheel bearings for SKF and Iljin, as well as product design and test lab management for GT Technologies.  He earned a B.M.E in 1989 from the Georgia Institute of Technology.
