Dr. Lauryn DeGreeff

Dr. Lauryn E. DeGreeff has worked in the field of analytical chemistry in support of canine detection for more than 13 years. She is currently employed as a research chemist at the U.S. Naval Research Laboratory and is on faculty of the Florida International University, Chemistry Department. Dr. DeGreeff received her Ph.D. in Chemistry with an emphasis in Forensic Science from Florida International University in 2010. Her research focused on the sampling, characterization, and delivery of human odor, living and deceased, for the purpose of canine detection. Following the completion of her doctorate, she worked as a research fellow at the Federal Bureau of Investigation, Counterterrorism and Forensic Science Research Unit. Her research focus was detection and determination of human scent and odor and human blood for the development / improvement of canine training aids and training methods. Dr. DeGreeff began her research at the U.S. Naval Research Laboratory in 2012 with focus on the characterization of explosives for instrumental and canine detection. She has since developed and patented a canine training tool for training on mixed odors, which has recently been brought to comme


A chemist’s perspective on the canine detection of explosives with considerations related to homemade explosives (HMEs)
Explosive detection canines are deployed to battle threats at home and abroad. They are utilized in the detection of explosive devices that threaten civilian and military personnel lives, as well as aviation and transportation security, such as landmines and improvised explosive devices (IEDs). The type of explosive materials most commonly encountered in the past included nitro-containing high explosives such as TNT and C4, or low explosives, such as smokeless and black powders. There is a significant body of research that has been carried out relating to the detection of these targets, which will be reviewed in this webinar.
As availability and ease of access to such explosives diminished, terrorists abroad began relying on homemade explosives (HMEs), assembled from easily attainable and commercially available materials. Use of HMEs is expected to continue to increase as such extremist groups continue evolving new methods improving predictability, long-term stability, and streamlined manufacturing of HMEs involving cheap, more easily accessible materials and less sophisticated equipment. Explosives detection capabilities have been slow to evolve with the changing threat. Considerations, including odor profiles, stability and degradation, and training aids related to canine detection of HMEs will be discussed. Finally, training aid selection and handling will also be covered.
