Peter McCourt is a Professor in the Department of Medical Biology at UiT, The Arctic University of Norway. Peter is teaching Biochemistry to Medical Laboratory Scientists and to Dental Nurses. He also supervises a number of PhD and MSc students. His current research involves developing super-resolution optical methods (SIM and dSTORM) for the study of liver sinusoidal endothelial cell (LSEC) fenestrations, and how they change with ageing. He is also studying endocytic processes in LSEC, and in their „cousins“, bone-marrow sinusoidal endothelial cells.
