Randy holds a Ph.D. in mechanical engineering, and for 30 years has been an automotive engineer at General Motors, where he is a technical specialist in noise and vibration (N&V) at their proving ground in Milford, MI. He has published numerous papers on powertrain N&V, and holds three patents. His first assignment at GM was the enviable task of developing Corvettes for minimized “rough road shake.” Randy sent this week's feature article on a Saturday evening, right in the middle of driving his Cayman in a 2-day track event at Putnam Park. So you know that he not only knows the theory, he drives the theory.
