About
Sys Stybe Johansen is a prominent forensic toxicologist whose research centers on the development and validation of advanced analytical methods for detecting drugs and toxic substances in biological matrices. Working primarily with whole blood, urine, and brain tissue, Johansen has made significant contributions to systematic toxicological analysis by leveraging cutting-edge technologies including ultra-high-performance liquid chromatography (UHPLC), time-of-flight mass spectrometry (TOF-MS), and automated solid-phase extraction (SPE). Her most cited work (78 citations) established a comprehensive forensic screening method capable of identifying 256 illicit and medicinal drugs in whole blood, streamlining laboratory workflows through full robotic automation. Building on this foundation, she developed targeted screening approaches for fentanyl and its analogues — a critically timely contribution given the global synthetic opioid crisis — earning 70 citations and demonstrating real-world applicability through retrospective forensic case analysis. Her validated quantification methods for post-mortem samples across multiple tissue types further underscore her commitment to rigorous, court-ready science. More recently, her work on drug-facilitated sexual assault cases highlights a dedication to justice-oriented forensic applications. Johansen's research collectively advances both the sensitivity and efficiency of forensic toxicological investigation.
