DeGreeff has worked in the field of analytical chemistry for more than 13 years with a research focus on trace vapor sampling, characterization, and generation in support of canine and other field detection approaches.  Dr. DeGreeff began her research career at Chapman University (Class of 2006) where she worked on diverse research topics under both Dr. Warren de Bruyn and the Kim Environmental Geochemistry Lab. She went on to receive her Ph.D. in Chemistry with an emphasis in Forensic Science from Florida International University in 2010 where her research focused on the sampling, characterization, and delivery of human odor, living and deceased, for the purpose of canine detection.  She then went on to complete a post-doctoral fellow at the Federal Bureau of Investigation, Counterterrorism and Forensic Science Research Unit. Dr. DeGreeff is now a research chemist at the Naval Research Laboratory where her research efforts are focused on the characterization of explosives and other chemicals for vapor detection. While at NRL, she developed and patented a canine training tool for training on mixed odors, which has recently been brought to commercial market. Additional research has included trace vapor and particle generation method development and characterization, as well as a chemistry-based approach to studying canine olfaction for the purpose of improving canine training and informing field vapor sampling practices.
