Professional Interests

Roy D. Marangoni’s main interests are mechanical vibrations, mechanical design, mechanical measurement theory and application, and biomechanics. He has taught a graduate course in orthodontic biomechanics and supervised graduate research in this area to the orthodontic residents since 1972. His other interests involve developing university/industry partnerships at both undergraduate and graduate levels.
