Dr. Shannon Kroeker is a biomechanical engineer and a member of MEA Forensic’s Injury Biomechanics group. Shannon investigates injuries related to vehicle collisions, child restraint system, sports and recreational accidents and slips, trips and falls. She uses her injury biomechanics expertise and engineering principles to determine the effect of forces upon the body. During her eight years at the firm, she has worked on more than 400 cases.

Shannon holds a Master of Applied Science from the University of British Columbia and a Doctor of Philosophy from the University of Washington in Mechanical Engineering. Her doctoral research involved measuring the injury thresholds of the spine and spinal cord. She has continued to pursue research at MEA, studying helmet effectiveness and publishing the results in peer-reviewed journals. “We are always working on research projects at MEA,” she says. “This satisfies both our own professional curiosity and provides us with specific insight into aspects of real incidents.”

With her background in experimental research, Shannon also makes use of MEA’s laboratory and testing facilities to answer questions related to specific cases when required. A crash test dummy, a linear sled, a helmet drop tower and a crash barrier are some of the tools that are available. “We can perform testing specific to the case,” she says.

Shannon began her career at MEA as a member of the Collision Reconstruction group providing her with an understanding of the dynamics of vehicle collisions and rollovers. Now in Injury Biomechanics, her investigations involve determining whether a particular injury is related to a particular incident. She also helps clients understand alternate scenarios. For example, if an individual were not wearing a seat belt, what would their injury risk have been had they, instead, been wearing their belt? “Often, we’re looking at whether someone would have been injured—or injured differently—in an alternate scenario,” says Shannon.
