John Scholtes
BSME 1982
Chief Engineer, Commercial Vehicles, Ford Motor Company

John Scholtes grew up on a farm in Granger, Indiana and came to Purdue in 1978.  After earning his BSME (and an MBA from the University of Detroit), he began his career with Ford Motor Company as an engineer in the Heavy Truck Engineering Office.  He has served in a variety of engineering, strategy, marketing/sales and general management positions with increasing responsibilities in Michigan, Indiana, California, Taiwan, England, Brazil, South Africa and China.

In his current role, he is responsible for total product program management, including product leadership, quality, fuel economy, customer driven features, product innovation and financial management.  John’s product portfolio includes Transit, E-350/450, F-650/750, and F53/9 Commercial Stripped Chassis that are built into motorhomes and delivery vans.  He also leads Ford’s Special Vehicle Engineering activity that designs unique fleet customer options, resulting in Ford’s leadership in commercial vehicle sales.

Throughout his career, John has operated with the mindset to “do what’s right for the customer.”  A good example of this was John’s Special Vehicle Engineering team adding wheelchair lifts to the internal employee shuttle fleet on the Dearborn campus, even though no budget was allocated.  Wheelchair bound employees can now receive a ride between buildings in 15 minutes versus previously having to book 48 hours in advance with a third party taxi service.

John has been happily married to Rebecca for 36 years (she is a Purdue grad, and her father John Held is a 1960 Purdue ME grad!)  They have four grown children and two grandchildren.  They are members of the John Purdue Club, President’s Council, and the Purdue Mechanical Engineering Advisory Committee. 


Robert Wade
MSME 1995
Engine Component Design Manager, Ford Motor Company

Robert Wade came to Purdue after finishing his BSME at Michigan Tech.  His thesis research was on effervescent atomization and combustion, working at Zucrow Labs (which then was called the Thermal Science and Propulsion Center).  He also earned an MBA from Michigan State University.

Robert began working at Cummins, on mid-range diesel engine research, seeking ways to implement advanced emission compliance technology.  He moved to General Electric Aircraft Engine division, designing combustion systems for military gas turbine engines.

He has now spent 18 years working on automobile engine technology at Ford Motor Company.  While at Ford, he has contributed to engine modeling, engine boost systems, thermal management, and component design.  Ford’s current Ecoboost engine lineup uses turbocharging, direct injection, and variable cam timing to make significant gains in energy efficiency.  

He has authored several technical papers and filed for over 35 patents.  In his current position in the United Kingdom, he is the department manager for engine component design including the engine cylinder block, engine cylinder head, valvetrain, crankshaft, piston, connecting rod, variable oil pump, bearings, cooling, drive systems, and the lubrication system.

Robert attributes many of the skills he utilizes today to his experience gained at Purdue.  The rigorous process that culminated in his thesis serves as a clear pattern for his current technical work: observation, hypothesis, controlled experiment, conclusion, and implementation.  This Purdue-taught process is still the model that guides his technological contributions in the automotive industry.
