Nathan Rose is a Partner, Director, and Principal Accident Reconstructionist at Kineticorp, LLC, an accident reconstruction, forensic engineering, and forensic visualization firm with offices in Los Angeles and Denver. Nathan helped found Kineticorp in 2005. Prior to that, he held positions as an engineer (1998 to 2003) and a senior engineer (2003 to 2005) at Knott Laboratory, another forensic engineering firm. He holds a bachelor’s degree in Engineering with a Civil specialty from the Colorado School of Mines (1998) and a master’s degree in Mechanical Engineering from the University of Colorado at Denver (2003). Nathan is accredited as a Traffic Accident Reconstructionist by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) and he has offered expert testimony as a reconstructionist in courts around the United States. During his graduate studies, he specialized in dynamics and impact mechanics and he has published numerous technical articles and reports related to vehicular accident reconstruction. These articles have covered many topics, including rollover accident reconstruction, motorcycle accident reconstruction, crash simulation, video analysis, crush analysis, restitution, and crash test sensor analysis. Nathan is a past organizer for the Rollover, Rear Impact, and Accident Reconstruction Sessions held annually at the Society of Automotive Engineers (SAE) World Congress. Nathan has published two books related to accident reconstruction: Motorcycle Accident Reconstruction and Rollover Accident Reconstruction. He teaches a three-day accident reconstruction course for SAE. Nathan holds a motorcycle endorsement in the State of Colorado and he has taken the Motorcycle Safety Foundation’s Basic and Advanced RiderCourses. You can download Nathan’s CV here.

Retain Nathan on a case

If you would like to retain Nathan to consult on an accident case, you can reach out to him by phone at (720)839-1995 or (303)733-1888, by email at, or by filling out the following form. If you fill out this form, Nathan will reach out to you. Please know that filling out this form does not constitute retaining Nathan on your case. Before he will consider himself retained, Nathan will need to discuss the case with you and have his assistant run a conflicts check. The form below requests the accident location, accident date, and legal case name, which will help us run this check. Nathan charges a $5,000 retainer to open a file. Nathan’s hourly rate is $300.

Nathan’s second book is called motorcycle accident reconstruction. You can purchase it here.

Some accident reconstructionists portray motorcycle accident reconstruction as a particularly esoteric topic, the purview of former elite motorcycle racers and guys that hang out at biker bars. The truth is that while there are certainly unique aspects to the way motorcycles handle, a well-founded reconstruction of a motorcycle accident is much like any other accident reconstruction - it is based on physical evidence and on fundamental principles of physics. Conservation of energy, conservation of momentum, Newton's laws of motion, empirical data and physical testing - these are at the core of motorcycle accident reconstruction, just as they are at the core of rollover accident reconstruction, heavy truck accident reconstruction, pedestrian accident reconstruction, roadside barrier impact reconstruction.

Of course, motorcycle accidents have their unique features and characteristics. For example, the rider is not attached to and contained by the motorcycle in the same way passenger car drivers are. Oftentimes, the rider will separate from the motorcycle and will physically strike another car or the ground. Also, the rider can weigh as much as the motorcycle does, and therefore, exert significant influence over the motion of the motorcycle. And, of course, let's not forget that motorcycles usually have only two wheels and they will usually capsize during the crash. Nathan's research has developed and documented methods for analyzing each of these occurrences.
