Dr Karin Tran-Lundmark is a pediatric cardiologist at Skåne University Hospital and Associate Professor at Lund University, Lund, Sweden. She received her MD/PhD degree from the Karolinska Institute in Stockholm. Her current clinical focus is pulmonary hypertension and advanced heart failure/transplantation. She spends 50% of her time in the clinic and 50% at the Biomedical Center in Lund conducting translational research. The main research focus is vascular remodeling in pulmonary hypertension and the role of the extracellular matrix in pulmonary vascular disease. Over the last few years Dr Tran-Lundmark and her group have started to use synchrotron-based phase contrast micro-CT for visualization of the vascular micro-anatomy in severe pulmonary hypertension. The imaging is non-destructive and can be combined with other methods like immunohistochemistry and RNAscope (in situ hybridization) to determine molecular mechanisms in search for potential therapeutic targets.
