Lena Claesson-Welsh

Lena Claesson-Welsh is a Professor in Medical Biochemistry at Uppsala University, affiliated with the Department of Immunology, Genetics and Pathology, where she leads the Vascular Biology research program. Her academic career includes roles at the Ludwig Institute for Cancer Research (1986-1996) and postdoctoral training at the University of Chicago (1984-1986). She holds a PhD from Uppsala University (1981-1984).

Her research focuses on molecular mechanisms of angiogenesis, vascular permeability, and tumor vascularization. Key interests include signal transduction pathways involving VEGF and endothelial cell dynamics. Her work integrates advanced imaging techniques like confocal and multiphoton microscopy.

Notable achievements include the Rudbeck Award (2014), Wallenberg Scholar title (2009), and Royal Swedish Science Academy membership (2003). Her group investigates therapeutic targets for diseases involving abnormal vasculature, such as cancer and inflammatory conditions.

Claesson-Welsh advises a team of researchers and collaborates internationally. Her lab's recent work highlights breakthroughs in understanding endothelial barrier function and lymphatic vessel metastasis mechanisms. Ongoing projects explore vascular normalization in tumors and the role of novel proteins like Neuropilin-1 in permeability regulation.
