Biography

Dr. McClintock teaches undergraduate classes in forensic sciences and microbiology and a graduate-level course in microbial pathogenesis. He previously held a faculty position in the Department of Molecular and Microbiology at George Mason University (GMU) in Fairfax, Va, where he taught graduate courses in forensic DNA analysis and in forensic sciences. The course in forensic DNA analysis focuses on current laboratory methods and applications in forensic DNA profiling and effective presentation of DNA evidence at trial. His previously published laboratory manual, entitled “Forensic DNA Analysis: A Laboratory Manual” (2008, CRC Press/Taylor & Francis), presents an overview of the current techniques and methods commonly used in forensic DNA typing, as well as, the interpretation of DNA evidence which is crucial for today’s criminalist. Dr. McClintock’s latest laboratory manual entitled “Forensic Analysis of Biological Evidence: A Laboratory Guide for Serological and DNA Typing” (2014) focuses on the current serological and DNA tests used in forensic laboratories throughout the world.

Dr. McClintock became Group Leader/Senior Staff Scientist at Digene Diagnostics, Inc. where he directed the research on the development and use of DNA probes for the detection and diagnosis of human pathogens

In 2013, Dr. McClintock was named among the top 15 DNA analysts in the country by ForensicColleges.com, a leading website on forensics programs across the nation. Dr. McClintock was recognized alongside professors from other prominent institutions across the U.S., including the University of California (Berkeley), Boston University, Penn State University, the University of Arizona, the University of North Texas, West Virginia University, and the University of Virginia. Criteria for the selection of these professors included practical experience outside the academic setting, involvement in cutting-edge research, and being published in academic journals.

In 2008, Dr. McClintock was invited to appear on the Nancy Grace Show to provide his insights on the use of DNA testing in the investigation of the missing 3-year old Florida girl named Caylee Anthony.
