Intermediate Associate, Biomechanics & Personal Injury
Direct: 647-738-5830

Our Associates perform on-site investigations to determine origin and cause of complex losses. Their process: examine and collect evidence, take on-site photos, interview witnesses, conduct testing in our lab and analyze data to produce technical reports that are clear and concise.


expert summary

Ms. Sinclair is an Associate with the Biomechanics & Personal Injury Group. She graduated from the University of Waterloo with a Bachelor of Applied Science in Mechanical Engineering, with a Biomechanics Option, in 2015. Her work experience includes research for the Department of National Defense focused on future small arms research projects and examining shooter response to weapon recoil and shooter performance. During her time with 30 Forensic Engineering, Brittany has conducted technical investigations involving the assessment of injury causation, including: pedestrian injuries, workplaces injuries, slips, trips and falls, head injuries, and injuries sustained in motor vehicle collisions.
