In this episode, podcast host Dr. Dwight Stoll talks with Dr. Katelynn Perrault, an Associate Professor of Forensic Science and Chemistry at Chaminade university in Honolulu, about her pathway to separation science, her research on the composition of odors from decomposing remains, and her thoughts about what the separation science community can do to get more women involved in the field. Drs. Stoll and Perrault talk about multi-dimensional gas chromatography (GCxGC)— which is Perrault’s primary research tool—ranging from where the technique stands today, to where progress will likely occur in the near future, and why the technique is so well suited to the analysis of decomposition odors.
