Dr.-Ing. Frank S. Dorer
Head of Directorate, Concept Development OBD
Dr.-Ing. Frank Dorer has studied aero- and astronautics at the Technical University of Munich. His doctor thesis at the same university dealt with combustion modelling of a hydrogen compression ignition engine used as a power supply for cargo vessels. Since 1999 Dr. Dorer is working for Volkswagen AG in the gasoline engine development. Starting with emission calibration Dr. Dorer switched to the scope of OBD, first calibrating of various concept and diagnostics of the Volkswagen Group. Since 2005 he deals with the OBD concept development at Volkswagen for gasoline concepts. Since 2008 Dr. Dorer is the head of the gasoline OBD concept development covering all gasoline related aspects for conventional, HEV and PHEV concepts for all worldwide markets.

John F. Van Gilder
Principal, Van Gilder Engineering, LLC.
John F. Van Gilder established Van Gilder Engineering in 2021 to support clients with professional consulting services for the development and implementation of on-board diagnostic systems (algorithms and hardware). The company is built on his 35 year career at General Motors, of which the last 30 years were devoted to developing and implementing on-board diagnostic systems for a variety of powertrain components (engines. transmissions, hybrid systems and energy storage systems, etc.). From 1996 to 2021, John served as the global lead development engineer at GM for on-board diagnostics. This included technical negotiations with global regulatory authorities, hardware design reviews for OBD compliance, and development of diagnostic algorithms.
Currently, through Van Gilder Engineering, John provides engineering support for the development, implementation, and verification of OBD systems including assessments of regulatory compliance. This support includes OBD performance (compliance and good design practice) reviews for diagnosed hardware, performance reviews for diagnostic algorithms, and critique of material prepared for CARB OBD regulatory staff review. Also, John supports several classes in OBD through SAE Continuing Education.
John earned a Bachelor of Science (magna cum laude) in Engineering Physics from University of Michigan (Ann Arbor) in 1980, a Master of Science in Nuclear Engineering from Bettis Atomic Laboratory (1982), and a Master of Science in Reliability Engineering from Kettering University (1990).
