Bjarke Jensen is a biologist trained in comparative physiology at Aarhus University, Denmark. He has been in the Netherlands since 2010 at the Academic Medical Center in Amsterdam. His research concerns the evolution of the heart from fish to man with focus on chamber junctions and septation of the atrial and ventricular chambers. Within this framework, there are currently two focuses. First, to uncover which adaptations enables mammals to have much higher heart rates than reptiles. Second, to characterize the anatomy, development, and physiology ventricular trabeculation. His research combines assessments of hemodynamics, electrophysiology, anatomy, and expression of genes and proteins.
