Stig Pedersen-Bjergaard

Stig Pedersen-Bjergaard holds dual academic appointments as a full-time Professor of Pharmacy/Drug Analysis at the University of Oslo (since 2000) and a part-time Professor (20%) in Analytical Chemistry at the Department of Pharmacy, Faculty of Health and Medical Sciences, University of Copenhagen (since 2008). His research focuses on pioneering microextraction technologies for sustainable analytical chemistry.

His academic credentials include:

• Master of Science (Chemistry), Technical University of Denmark, 1990
• Doctor Scientiarum (Analytical Chemistry), University of Oslo, 1995

Professor Pedersen-Bjergaard's research centers on conceptual development of microextraction systems based on mass transfer across artificial liquid membranes, downscaled to nano- and microliter volumes. His group invented liquid-phase microextraction (LPME) and electromembrane extraction (EME), which provide green, selective sample preparation for next-generation analytical chemistry. Applications primarily target pharmacy and biomedicine using liquid chromatography-mass spectrometry, with recent commercialization of EME technology driving increased adoption.

His 2024-2026 publications reveal strong trends toward electromembrane extraction optimization, green chemistry assessment, and high-throughput applications in pharmaceutical, food, and forensic analysis. Key subfields include nanomaterial-enhanced membranes, multi-class veterinary drug screening, and volumetric microsampling for blood analysis.

He leads the Microscale Analytical Systems research group, operating the Drug Metabolism Lab at the University of Copenhagen in collaboration with the University of Oslo. His editorial roles include Trends in Analytical Chemistry, Advances in Sample Preparation, and Journal of Pharmaceutical Analysis, while his teaching covers bioanalytical sample preparation techniques.
