Courtney Kersten-Kwan M.Sc.

Senior Associate, Human Factors
Direct: (416) 368-1700

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.



Ms. Courtney Kersten-Kwan is a Senior Associate in 30 Forensic Engineering’s Human Factors group. Courtney graduated from McMaster University with a Bachelor of Kinesiology (minor in Psychology) and Master of Science in Human Biodynamics (Psychomotor Behaviour). In 2008, she additionally obtained a Master of Science in Ergonomics (Human Factors) from Loughborough University, England. Prior to joining 30, Courtney has worked as a Human Factors consultant/specialist providing human factors design and experimental support across a variety of contexts and important sectors including emergency services, healthcare, nuclear, public transit, and armed forces. Recently, Courtney developed a fatigue management program for a large transit authority, to proactively mitigate risks associated with fatigue, particularly of importance were those impacting human performance and safety. Courtney has additionally worked within Canadian regulated safety management systems where she developed and refined her investigative and auditing skill sets.
