Title: Challenges in Forensic Separations
Abstract: The popularity of forensic science on TV shows and movies has glamorized forensic scientists and their work for the last couple of decades. But can you really inject a DNA sample in your GC and instantly obtain the name and address for the criminal? Can your arsenal of instruments perform an analysis and find a chemical database for every reference material related to the evidence? While practicing chemists recognize that this is not the case in real life, we can be thankful that these TV shows inspire many young people to seek careers in science. Research in forensics manifests many challenges as new and unusual samples present themselves in casework. One of the first tasks of a researcher is to determine what is the relevant target molecule(s) and what is the matrix one must analyze? Often in casework these are common matrices such as biological material (e.g. blood, urine, etc.) or an environmental sample (e.g. soil, water, etc.). But many times there is a twist to the complexities of getting the right results. For example, who could have foreseen that one day we would need to or be able to detect drugs in bugs or hair? Forensic chemistry research deals with these challenges by developing new methods that require both a separation of a complex mixture and a detection technique. The evolving threats mean that both small and large, organic and inorganic chemicals must be separated and analyzed for evidence examinations. GC and LC are the most useful tools for the separation of complex mixtures for everything from hydrogen peroxide to ricin. One of the tricks to effective use of chromatography is to have adequate retention of your analyte on the separation column, which from review of the literature is not always present in forensic practice. This talk will provide real examples of improved and new methods developed for different types of evidence for application in toxicology and explosives casework.
Bio: Mark L. Miller is a Research Chemist at the FBI Laboratory's Counterterrorism and Forensic Science Research Unit in Quantico, Virginia. He has been working on various chromatographic and mass spectrometric applications in forensic science since joining the FBI in 1992. His research interests include trace analysis in toxicology, drugs, explosives, chemicals and materials. Prior to working at the FBI, he was a Senior Research Chemist for Monsanto Chemical Company in the R&D group. Dr. Miller received a Ph.D. in Analytical Chemistry from the University of North Carolina in Chapel Hill where he was under the direction of Professors Richard Linton and James Jorgenson. He has a B.S. in Chemistry from Indiana University in Bloomington and did research in Professor Milos Novotny's lab. He is an avid Tarheel fan and from a family of UNC graduates or impending graduates.
2016 Open House & Poster Session
