Professor Dr. Bourauel is physicist and affiliated with the Dental Clinic at the University of Bonn since 1987. After heading the Orthodontic Biomechanics Laboratory for more than 15 years, he took over the Endowed Chair of Oral Technology at the University of Bonn in October 2006. The main focus of his scientific work lies in the fields of dental biomechanics and materials science, with a focus placed on orthodontic superelastic nickel titanium alloys, friction in arch guided tooth movement, and theoretical modelling of orthodontic tooth movement as well as bone/implant interactions. Dr. Bourauel has published more than 250 papers in national and international journals in orthodontics, biomechanics, biomedical engineering, and materials science and has around 600 interdisciplinary oral and poster presentations on Congresses and Symposia. Together with various co-workers he received several awards, beside them the Best Paper of the Year Award of the German Association of Orthodontists (DGKFO) in 1990 and 2014, the Helen and B.S. Dewel Award of the AAO in 1992, the Implant Dentistry Award of the German Association of Dental Implantology (DGZI) in 2007, the Distinguished Teacher Award of the European Orthodontic Society (EOS) in 2007, and the International Clear Aligner Research Award in 2011.
