Dr. Cornel de Jongh is a biomedical engineer with 20 years of experience in the biomechanical engineering field. He specializes in injury biomechanics, biomechanical analysis, mechanisms of injury, computational modeling, automotive (motor vehicle and motorcycle) safety and analysis, sports-related injury, and passive occupant restraints. Prior to joining SE Forensic, he has been extensively involved in subject-matter expert witness consultation, as well as the design, development, and testing of safety products, particularly for the head, neck, shoulder, knee, and ankle. He has conducted research in injury mechanics of the neck as a Senior Lecturer at Stellenbosch University – Stellenbosch, South Africa, where he also taught various biomedical and mechanical engineering courses. Dr. de Jongh continues to act as an external examiner for the University of Cape Town’s Faculty of Health Sciences.
Dr. de Jongh is listed as the co-inventor in four granted patents and four patent publications, of which one has gone on to win numerous trade awards for motorcycle safety innovation. He has been invited to present his work on neck injury prevention at international conferences and as a keynote speaker, including at the Mayo Clinic (Rochester, MN) and the International Spinal Cord Society’s (ISCoS) annual scientific meeting, where he was invited to present his work on the development of a novel neck brace to reduce the risk of cervical spine injury in off-road motorcycle riding.
Dr. de Jongh has testified in trial as a subject-matter expert witness in the USA and South Africa and has acted as a consulting expert in the field of injury biomechanics and product design on many other occasions.
Dr. de Jongh is fluent in English and Afrikaans.
