John Bjarne Hansen

Professor John Bjarne Hansen is a prominent researcher in the field of venous thromboembolism (VTE) at the Department of Clinical Medicine, UiT The Arctic University of Norway. He serves as Research Group Leader of Thrombosis Research (TREC) and Head of Unit at the Thrombosis Research Center (TREC), Medical Clinic, University Hospital of Northern Norway.

Education:

• Cand.med (MD), Universitetet i Tromsø (1989)
• Dr. med (PhD in Cardiovascular Medicine), Universitetet i Tromsø (1997)

Hansen's research focuses on clinical epidemiology and risk factors for venous thromboembolism, diagnostic and predictive biomarkers for VTE, and the pathophysiology of thrombotic events. His work spans multiple projects including PREVENT, Mission-VTE, Genetics and VTE, Biomarkers of VTE risk, and Cancer-associated VTE. He has contributed significantly to understanding the complex interplay between genetic factors, lifestyle, and comorbidities in VTE development.

His recent publications demonstrate a strong focus on biomarkers for VTE prediction, with numerous 2024-2025 articles examining genetic, molecular, and clinical risk factors. His research utilizes large population studies like the HUNT and Tromsø studies to identify novel predictors and understand gender differences in VTE risk.

Hansen has made substantial contributions to thrombosis research through his leadership of the Thrombosis Research Center (TREC) and through active participation in international collaborations. His work bridges basic science and clinical application, with emphasis on translating research findings into improved risk prediction and prevention strategies for venous thromboembolism.

Mentorship and Academic Leadership:

• Primary supervisor for 35 completed PhD theses
• Co-supervisor for 5 completed PhD theses
• Currently supervising 7 PhD students as primary supervisor and 6 as co-supervisor
• Mentored 13 postdoctoral researchers (10 former, 3 current)

He has held various academic positions since 1991, progressing from doctoral student to full professor, with a visiting professorship at The Scripps Research Institute (2008-2009). From 2007-2008, he served as Pro-Dean for Research at the Faculty of Health Sciences.
