Nikolai Stephanson is a Researcher affiliated with the Department of Laboratory Medicine at Karolinska Institutet, based in Stockholm and Huddinge. His work focuses on clinical pharmacology, specializing in advanced analytical methods for drug detection in biological samples.

Education

• Doctor of Philosophy, Department of Medicine, Solna, Karolinska Institutet (2007)
• Licentiate Degree, Department of Medicine, Solna, Karolinska Institutet (2004)

Stephanson's research centers on Pharmacology and Toxicology, with expertise in mass spectrometry (LC-MS/MS, LC-HRMS) for detecting drugs of abuse in urine, exhaled breath, and oral fluids. His studies frequently address pharmacokinetics of opioids (e.g., ketobemidone, ropivacaine) and analytical method validation for clinical and forensic applications.

An analysis of his 15 most recent publications (2010–2025) reveals dominant themes: analytical chemistry innovations (e.g., high-throughput screening, non-invasive breath testing), pharmacokinetic studies in surgical/neonatal contexts, and forensic toxicology focused on novel psychoactive substances. Recurring methodologies include multi-analyte LC-MS/MS workflows and biomarker quantification.

No scientific awards, grants, or student advising roles are documented.

He operates within the Division of Clinical Pharmacology at Karolinska Institutet, collaborating on interdisciplinary projects linking laboratory medicine, anesthesiology, and public health.
