Prof. Dr. Margret Thorsteinsdottir

Margrét Thorsteinsdóttir is a Professor of Pharmaceutical Analytical Chemistry at the Faculty of Pharmaceutical Sciences, University of Iceland, and the founder and R&D Director of ArcticMass Ltd. She earned her PhD in 1998 from Uppsala University, Sweden. From 2000 to 2009, she served as Managing Director of the Bioanalytical Laboratories at deCODE Genetics in Reykjavík, gaining broad experience in developing bioanalytical methods for quantifying clinical biomarkers in diverse biofluids. Her work integrates analytical chemistry and chemometrics to support improved clinical decision-making and advance personalized patient care. Her current research focuses on profiling plasma-derived biomarkers for early detection of BRCA-related breast cancer and developing targeted mass spectrometry–based proteomic platforms to investigate associations between circulating proteins and incident myocardial infarction. She leads e􀆯orts to implement clinical mass spectrometry to support diagnostics and therapeutic drug monitoring through collaborations with ArcticMass and Landspítali – The National University Hospital of Iceland, emphasizing integrated multi-omics workflows for early disease detection. Margrét is also a co-founder of Females in Mass Spectrometry (FeMS) and recently established a mass spectrometry section within the Icelandic Chemical Society, including a dedicated proteomics division.
