Peter McCourt

Peter McCourt is a Professor in the Department of Medical Biology at UiT The Arctic University of Norway. His research focuses on liver sinusoidal endothelial cells (LSECs), their role in scavenging pathogens and toxins, and the application of advanced microscopy techniques to study cellular ultrastructure. Key areas include aging-related changes in LSEC function, nanotherapeutic delivery systems targeting the liver, and the interplay between hemodynamics and liver architecture.

Research interests span liver biology, endothelial cell biology, and biomedical imaging innovations. His work combines experimental and computational approaches to understand how LSECs regulate blood filtration, immune responses, and metabolic processes. Notable contributions include developing optical microscopy methods like transparent polymer waveguide chips for super-resolution imaging and investigating nanoparticle-mediated drug delivery to rejuvenate aged liver cells.

Publications highlight advancements in correlative microscopy, fenestration dynamics in LSECs, and the role of stabilin receptors in scavenging oxidized proteins and viral particles. His research bridges basic science and translational medicine, addressing applications in aging populations and infectious diseases.
