Research efforts in our group are centered in the main scope of "volatolomics", specifically in the analysis of volatile organic compounds from biological as well as other forensic specimens which could yield a chemical odor profile useful for discriminatory and identification purposes. To achieve these objectives, the analytical methods implemented in our laboratory include the use of instrumentation such as gas chromatography/mass spectrometry and solid phase microextraction that allow the efficient extraction and detection of target analytes with minor sample disturbance. Our particular interest is in understanding the complex odor picture available to the canine nose in the many military and law enforcement applications of working dog canine teams. Additionally, we are focusing our efforts on not only the analytical chemistry component, but also in monitoring canine response and threshold levels with concurrent canine field testing.
One major subject of study in our laboratory is that observed in the ares of forensic odorology. A young discipline in the Western hemisphere, this area of forensic science focuses on the evaluation of human odor volatiles as a biometric measurement to discriminate individuals. Using traces of odor to detect and prosecute criminals, establish connections between victim-assailants, and ultimate detection, and preservation is the fundamental reasoning for all our experimental designs. Since the beginning stages of this work, we are now in a position to further exploit a subject's odor profile and target the analysis to extract more information from an odor sample, ranging from questions stemming from disease conditions, addiction, and even geographical origin.
Additionally, we have undertaken a series of new studies to look at both odor profiling and fingerprint development as they relate to sexual assault evidence items. With the emergence of DNA applications, some of the more traditional forensic techniques such as fingerprinting sometimes get shadowed, hence, it is the intent of our approaches to highlight potential sources of new evidentiary tools sampling novel substrates via both powdering and chemical techniques.
