Course Description
Analytical measurements play an important role in the scientific quantitative analysis of many types of forensic samples and trace evidence. The interpretational value and scientific validity of analytical measurement results introduced in court cases through expert witness testimony can impact bench and trial outcomes. As an enabling science inherent in sound laboratory operational systems, metrology provides the rigorous basis for the scientific credibility and defensibility of measurement results when they are challenged through intense direct and cross examinations. This course provides a basic introduction to chemical metrology and its relevance to the many facets of the overall analytical forensic measurement process involving quantitative chemical analysis. Courtroom outcomes involving the application of metrology in the determination and reporting of breath and blood alcohol content, seized drug testing and chemical analysis in other forensic science disciplines will be presented.

Target Audience
This introductory one-day course will benefit forensic science students, crime laboratory analysts and supervisors, criminal defense attorneys, young prosecutors from district attorney offices, judges, quality assurance personnel and laboratory accreditation auditors.

Course Instructor's Biography
Jerry Messman earned a PhD in analytical chemistry from the University of Maryland (College Park, Maryland USA). Jerry’s professional career in analytical chemistry and metrology includes dual tenures as a Research Chemist with the National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS), where he participated in the certification of chemical Standard Reference Material (SRM) artifacts. Jerry also directed the NIST certification and renewal of hundreds of optical SRM transfer artifacts intended for the performance evaluation and qualification of analytical UV/VIS absorption spectrophotometers. A growing part of his current responsibilities and interest involves educational outreach and consulting in forensic science where he instructs criminal defense attorneys and government agency stakeholders on the key concepts of chemical forensic metrology and its critical role in crime laboratory testing and expert witness testimony. Jerry is a qualified forensic expert witness in the Commonwealth of Pennsylvania.
