Dr. Katelynn A Perrault is Associate Professor of Forensic Sciences and Chemistry and joined Chaminade University of Honolulu in January 2017. She is the Principal Investigator of the Laboratory of Forensic and Bioanalytical Chemistry, which focuses on using multidimensional chromatography to uncover volatiles as mediator chemicals in processes associated with life, health and death. Through her research, Dr. Perrault has cultivated an international network of collaborators in academia, police, and government agencies. She typically teaches courses in Instrumental Analysis, Chemical Measurement, Forensic Chemistry, Professional Preparation, as well as Seminar, but also has taught courses in General Chemistry, Analytical Chemistry, Biological Chemistry for Nurses, Physical Evidence, and Internship. She is known for incorporating high impact practices into her classes such as course-based undergraduate research experiences, culturally sustaining pedagogy, gamified learning, and project-based learning.
Dr. Perrault has expertise in the use of gas chromatography (GC) and comprehensive two-dimensional gas chromatography (GC×GC) across a range of chemical forensic and biomedical applications. Dr. Perrault is internationally recognized by a number of awards, including the 2018 Top 40 Under 40 (The Analytical Scientist), the 2019 Satinder Ahuja Award for Young Investigators in Separation Science, the 2021 John B. Phillips Award, and the 2021 Henry Dreyfus Teacher-Scholar Award. Institutionally, Dr. Perrault has been recognized with the 2021 Fr. John F. Bolin Award for scholarly work, the 2021 Distinguished Faculty Award, as well as the 2021 President Mackey Award for outstanding mentorship. She volunteers regularly for events related to the promotion of science to the general public and was recognized in 2021 as Outreach Volunteer of the Year by the American Chemical Society. Dr. Perrault has a diverse research funding portfolio, having been supported by a National Science Foundation CAREER award, the Camille & Henry Dreyfus Foundation, the Society of Analytical Chemists of Pittsburgh Undergraduate Analytical Research Program, the Hawaii Community Foundation Leahi Fund to Treat & Prevent Pulmonary Disease, and more.
