Dr. Katelynn A Perrault, Assistant Professor of Forensic Science and Chemistry, earned her BSc (Hons) in Forensic Science from the University of Ontario Institute of Technology (UOIT) in 2011. She earned her PhD from the University of Technology Sydney (UTS) in 2015 with a focus on forensic chemistry. Following her doctoral work, Dr. Perrault performed doctoral studies at the University of Liège, applying novel analytical approaches to challenging matrices in various fields such as food science, archaeology and forensic science. Through her research, Dr. Perrault has cultivated an international network of collaborators in academia, police, and government agencies.

Dr. Perrault has expertise in the use of gas chromatography (GC) and comprehensive two-dimensional gas chromatography (GC×GC) across a range of life science applications, including primarily forensic science. She has done extensive work profiling the volatile organic compounds (VOCs) that form the odour evolved from decomposing remains. Such work is essential in understand the sensory mechanisms behind scent-detection canine use. Dr. Perrault’s research program at Chaminade focuses on sensing VOCs from various biological sources for medical and forensic applications. Dr. Perrault is a peer-reviewer for several forensic science and chemistry journals and has presented at numerous international conferences. Dr. Perrault is funded by the Hawaii Community Foundation Leahi Fund to Treat & Prevent Pulmonary Disease, as well as the National Science Foundation CAREER program, and is dedicated to the mentoring of undergraduate research students in the Natural Sciences.
