Nathan Rose is Director and Principal Accident Reconstructionist at Kineticorp, a firm that he co-founded in 2005. Mr. Rose has been reconstructing vehicular crashes since 1998. He holds degrees in both Civil and Mechanical Engineering and he is an accredited Traffic Accident Reconstructionist. During his graduate studies, Mr. Rose specialized in dynamics (the study of motion) and impact mechanics (the study of how objects respond to impacts). He has extensive experience analyzing and interpreting physical evidence related to vehicular crashes as well as modeling and analyzing crashes with physics-based computer simulation. In the summer of 2009, Mr. Rose received an appointment as a Lecturer in the College of Engineering and Applied Science at the University of Colorado at Denver and taught a course on impact analysis. He currently teaches the Society of Automotive Engineers’ (SAE) course on reconstructing rollover crashes.
Mr. Rose has published numerous technical articles and reports related to vehicular accident reconstruction. These articles have been published in the SAE International Journal of Passenger Cars – Mechanical Systems, in the SAE Technical Paper Series, in Accident Investigation Quarterly, in the Proceedings of the International Crashworthiness Conference, and in Collision – The International Compendium of Crash Research. Topics covered in these articles include the accuracy of witness distance estimates, rollover crash dynamics and simulation, vehicle damage analysis methods, impact restitution, tire mark characteristics, critical speed analysis, spinning vehicle deceleration rates, motorcycle crash causation, photogrammetry, and video analysis. Mr. Rose also acts as a peer reviewer for technical papers published by the SAE. In the last 8 years, he reviewed 45 technical papers written by his peers. These reviews have been for the Accident Reconstruction (2007-16), Safety Test Methodology (2009, 2011), Rollover (2008-14) and Rear Impact (2009) Sessions for the annual SAE World Congress. Mr. Rose is a member of the SAE Occupant Protection Committee and an organizer for the Accident Reconstruction Session at the annual SAE World Congress (Since 2013). He is a past organizer for the Rollover and Rear Impact Sessions, also held at the SAE World Congress (2008-09).
Mr. Rose’s education, experience, research, and professional volunteer activities have laid the groundwork for the admission of his accident reconstruction work and testimony in courts around the country.
