Thomas Jonassen

Thomas Jonassen serves as an Associate Professor in the Department of Biomedical Sciences within the Faculty of Health and Medical Sciences at the University of Copenhagen. His research is centered in the Renal and Vascular Research group, where he investigates cardiovascular and renal physiology with particular focus on drug mechanisms and physiological regulation.

Jonassen's research interests span renal physiology, vascular function, and pharmacological interventions. His work examines how the kidneys handle sodium under sympathetic stimulation, the effects of drugs like melanocortins and GLP-1 analogs on kidney function, and cardiovascular regulation mechanisms. He employs both basic science approaches using animal models and clinical trial methodologies to translate findings to human applications.

Analysis of his recent publications reveals a strong focus on translational research connecting basic physiological mechanisms with clinical applications. His work demonstrates consistent expertise in renal hemodynamics, autonomic regulation of cardiovascular function, and pharmacological interventions for conditions including hypertension, diabetes, and inflammation. The research shows progression from fundamental physiological questions to clinical trials, particularly evident in his 2024 COVID-19 therapeutic study.

Jonassen maintains active collaborations with researchers across the University of Copenhagen, particularly with N.-H. Holstein-Rathlou and C. M. Sørensen, demonstrating a strong network within renal and cardiovascular research. His publications have garnered significant attention, with several papers accumulating substantial citations and mentions in social media, news outlets, clinical guidelines, and policy documents.
