Independent consulting services, 2001-Present. Currently employed by Ralph Cunningham, Inc.


Self-employed (2001-present)

As an independent consultant, I have endeavored to develop/refine/improve my skills, knowledge base, hardware, and software to provide better service in accident reconstruction and motor-vehicle-related forensic consulting. In 2002, I acquired a Crash Data Retrieval system and associated training, and I have maintained Technician and Analyst certification with that hardware and software. I have maintained my ACTAR Accreditation by renewing every five years. Renewal requires 80 contact hours of reconstruction-related continuing education or a retest; I have chosen the continuing-education option. I have expanded my awareness and capabilities in the realm of human factors in the driving environment by seminar attendance at offered courses and by being one of the first to purchase a new, commercial software product (I*DRR) for predicting driver reactions and responses based on tens of thousands of studied, real cases. I have had a Vericom VC3000DAQ accelerometer for years, and I recently upgraded to the phenomenal VC4000DAQ. I began my independent practice using a Sony A900 digital single-lens-reflex camera which has a full-frame (24 by 36 mm) CMOS image sensor with 24.6 megapixel resolution. My primary lens was a Sony 28-75 f/2.8 constant aperture auto-focus zoom. I have since purchased a number of more modern digital cameras, the most advanced of which is a Sony a7R. I have attended numerous collision seminars which involved staged collisions which were subsequently analyzed in minute detail. I have also attended numerous other seminars and courses to stay current with the latest developments in the art and science of motor vehicle accident reconstruction, which fields continue to grow. Since becoming an independent, I have become a Fellow (requiring peer review of a sample of my work and verification of my testimony at trial to those peers by an attorney) in the International Association of Accident Reconstruction Specialists (apparently the oldest such organization in North American) in addition to becoming the Secretary/Treasurer for that group, as well as being a member, officer, or participant in other societies and organizations.. I continue to provide expert testimony in accident reconstruction, tire failure, lamp filament evaluations, and similar matters in state and Federal courts in the southeastern United States.

Cerny & Ivey Engineers, Inc. (1972 - 2001)

Diversified consulting engineering experience involving physical testing of materials and systems; fire investigations and damage evaluations; accident reconstruction; failure analysis; model and exhibit preparation; surveying of accident sites; boiler failure evaluation; tire testing, research, and examination; seismologist in ground and structural vibrations from blasting, pile driving, machinery movement, etc.; pre-construction surveys; structural evaluation of vibration damage; vehicle component failure analysis; modular and mobile home design evaluation, testing, and certification; flammability testing of materials. In the last 15 years, focus was increasingly on motor vehicle accident reconstruction and vehicle component failure evaluations while I was employed as Senior Staff Engineer. Also served on Board of Directors, as Corporate Secretary, and as Webmaster.

Engineering Design (1968 - 1971)

As a cooperative student, was employed by Georgia Power Company Central Engineering and by American Can Company Project Engineering, Naheola, Alabama. Experience included plan and profile drawings; cut and fill drawings and calculations; ash pond life expectancy studies; floodplain property maps; railroad design and layout; machinery and equipment design and location planning; piping design and drawing; maintenance engineering assistance. During this period became familiar with various aspects of civil, mechanical, and electrical engineering. Acquired knowledge of paper mill operation, including power and recovery boilers, pulp and paper machines, water treatment, materials handling equipment and systems, pulp digesters, and cooling towers.
