Dr. Barry Logan began his career in forensic toxicology studying under Dr John Oliver and Dr Hamilton Smith, at the prestigious Department of Forensic Medicine and Science at Glasgow University. His first job in forensic toxicology was collecting and testing urine from racing greyhounds at Glasgow's Shawfield Stadium. He learned the basics of forensic toxicology from his mentors, developing new methodologies and studying Scotland's opioid crisis of the 1980's. On completion of his PhD, he took this experience to the United States in 1987, studying under another famous toxicologist, Dr David Stafford at the University of Tennessee in Memphis. Stafford, a protege of Dr Harold McNair, one of the first toxicologists to introduce gas chromatography testing for toxicology investigations. Dr Logan began his prodigious publication record in forensic toxicology at UT, and created novel approaches to drug testing in postmortem investigations. In 1990, Dr Logan took his career to the next level when he was recruited to the University of Washington in Seattle, as Washington State Toxicologist. He immediately became a leader in the emerging field of drugs and driving impairment. Over the next twenty years he published over 100 papers in the fields of postmortem toxicology, driving impairment, and most recently designer drugs or new psychoactive substances. He has been recognized for his leadership in these fields by being elected as President of the American Academy of Forensic Sciences in 2013. AAFS is the worlds premier professional organization in forensic science with over 7,000 members worldwide.

Dr Logan is currently the Chief Scientist at NMS Labs and Senior Vice President of Forensic Sciences, where he leads a team of world leading scientists in its research and development forensic consulting divisions. A highly sought after speaker in the areas of drugs and impairment and designer drugs, he lectures all over the world. He is currently assisting several professional, state and federal investigative agencies and death investigators on providing better testing in today's opioid crisis in the United States, and helping to understand the toxicity of these substances in assessing cause and manner of death.
