Scott Kriger, Ph.D. Toxicologist E-mail: skriger@aitlabs.comRead more about Dr. Kriger’s background
Scott Kriger, Ph.D. brings more than ten years of experience in drug development and toxicology to AIT. He joined the company in 2007 after spending two years with the Tennessee Bureau of Investigation, testing samples for blood alcohol content and other drugs of abuse and performing analyses using gas chromatographer/mass spectrometers and gas chromatographers with flame ionization detection. Other professional experience includes serving as a principle scientist for Hoffman La Roche Pharmaceuticals, where he supervised the development and validation of analytical methodologies for new chemical substances, and working as a senior research scientist for Solvay Pharmaceuticals in Atlanta, Georgia, managing the drug product development group and providing technical leadership over the testing of raw materials for clinical trial.
Kriger earned his bachelor's degree in chemistry from the University of Central Florida and a doctorate in analytical chemistry from the University of Tennessee, where he was presented with several awards for outstanding coursework and research. He currently holds membership with the International Crime Scene Investigation Association and has been active in several professional groups, including the American Chemical Society, American Society for Mass Spectrometry, and the American Association of Pharmaceutical Scientists. He's also presented on various pharmaceutical- and toxicology-related subjects at conferences throughout the country.
Josh Gunn, Ph.D. Toxicologist E-mail: jgunn@aitlabs.comRead more about Dr. Gunn’s background
Toxicologist Josh Gunn, Ph.D. began working at AIT in 2007. Lab experience includes method development and operation of analytical instrumentation including gas chromatography, high-performance liquid chromatography, gas chromatography/mass spectrometry, liquid chromatography/mass spectrometry, liquid chromatography/tandem mass spectrometry, and ultra performance liquid chromatography/tandem mass spectrometry. Originally from Australia, he holds bachelor’s degrees in analytical chemistry and forensic science from Deakin University in Geelong and a doctorate in analytical chemistry from West Virginia University, and he worked with the Victorian Institute of Forensic Medicine in Melbourne to test alternative toxicological specimens for drugs in cases where the cause of death was not confirmed. Gunn’s research was successful and soon found an audience in the Journal of Analytical Toxicology, where he has since published research on the detection of drugs of abuse in meconium.
Gunn’s professional memberships include the American Academy of Forensic Sciences (Toxicology).
Gene Schwilke, Ph.D.Toxicologist E-mail: eschwilke@aitlabs.com
Read more about Dr. Schwilke's background
Gene Schwilke, Ph.D., joined AIT in 2008, bringing with him more than fifteen years of experience in forensic toxicology. His background includes eleven years at the Washington State Toxicology Lab, where he began his tenure as a college research assistant and eventually advanced to forensic toxicologist, and a wealth of research for the National Institute on Drug Abuse (NIDA) as part of his dissertation for his Ph.D. in forensic toxicology. The majority of Schwilke’s research was based in cannabinoids. Current research topics include studying plasma concentrations in frequent cannabis users during continuous controlled oral THC administration and looking at predictive models for differentiating recent cannabis use from residual drug excretion. He has published articles and given presentations on drugs and impairment on international, national, and regional levels. He is also certified by the American Board of Forensic Toxicology (ABFT).
Schwilke holds a bachelor’s degree in wild life science from the College of Forest Resources at the University of Washington and a Ph.D. in forensic toxicology from the University of Maryland.
George S. Behonick, Ph.D., DABFT Toxicologist E-mail: gbehonick@aitlabs.com
George S. Behonick, Ph.D. joined AIT in November 2009 and brings more than eleven years of experience. He comes to the company after most recently serving as the director of forensic toxicology at UMass Memorial Medical Center Department of Hospital Laboratories and assistant professor of pathology at the University of Massachusetts Medical School in Worcester, Mass., since January 2005.
Prior to that, Behonick was a forensic toxicologist for six years with the Virginia Department of Forensic Science Western Laboratory in Roanoke, Va. This period of time included extensive experience in complex postmortem drug-related cases, notably involving the opiate and opioid classes, extensive scientific expert witness testimony in driving under the influence (DUI/DUID) of alcohol and/or drug(s) criminal court cases.
Behonick earned his bachelor’s degree from The Citadel in Charleston, S.C.; his master’s degree from Hahnemann University in Philadelphia, Pa.; and his doctorate from St. John’s University in Queens, N.Y. In 1998, Behonick completed a postdoctoral research associateship through the National Research Council/National Academy of Sciences at the United States Army Medical Research Institute of Chemical Defense, Aberdeen-Edgewood Area, Md. He also holds diplomate status with the American Board of Forensic Toxicology (ABFT).
Lynn Willis, Ph.D.Pharmacologist E-mail: lwillis@aitlabs.com
Lynn R. Willis, Ph.D., joined AIT Laboratories in January 2010, three years after retiring from the faculty of the Indiana University (IU) School of Medicine, where he was a professor of pharmacology in the Department of Pharmacology and Toxicology for thirty-three years. While on the IU faculty, Willis directed a medical pharmacology course for second-year medical students for twenty-nine years, receiving numerous teaching awards for his efforts. He also directed and taught graduate courses in pharmacology and conducted basic pharmacological and physiological research in areas that include blood pressure control, renal tubular function, and shock wave lithotripsy. He has nearly 100 scientific publications to his credit and currently offers CME lectures to health professionals on herbal pharmacology and alternative medicine.
Willis completed his bachelor’s degree in pharmacy from Oregon State University in 1966, earned a Ph.D. in pharmacology from the University of Iowa in 1970, and completed two and a half years of postdoctoral training in physiology at the Mayo Clinic prior to taking the faculty position with IU. He is a member of the American Society for Pharmacology and Experimental Therapeutics and the American Society of Nephrology, among other professional societies. He currently serves on the Controlled Substances Advisory Committee for the Indiana Board of Pharmacy.
