Ms. Arianna McAllister is a project engineer in the Collision Reconstruction group. From the Toronto office, she assists with the investigation of accidents involving cars, motorcycles, bicycles, pedestrians, and recreational vehicles, such as ATVs and snowmobiles. She helps document and analyze evidence to determine the circumstances of an accident.

Solid answers start with well-documented evidence. “We’re very good at collecting and assessing physical evidence,” Arianna says. She routinely downloads “black box” crash data from vehicles and uses a 3D scanner to document crash damage and accident locations. Arianna also considers new sources of evidence such as dashcam video and cell phone apps that record the speed and location of runners and cyclists. Once the evidence has been documented, Arianna helps interpret it using engineering principles and physics-based computer simulation software. The result is a clear description of what happened.

Arianna has a Bachelor’s degree in Biomedical Mechanical Engineering from the University of Ottawa and a Master’s degree in Biomedical Engineering from the University of Toronto. Work on her Master’s thesis helped her develop critical thinking skills. “My master’s was really a self-directed research job,” she observes. Arianna enjoys the mathematical and hands-on problem-solving aspects of her work at MEA. “There is no such thing as a typical case and I have to answer new questions for each one; I enjoy that challenge.”
