Henrik Peter Sahlin PettersenView profile
Associate Professor
Henrik Peter Sahlin Pettersen is an Associate Professor at the Norwegian University of Science and Technology (NTNU), affiliated with the Department of Clinical and Molecular Medicine within the Faculty of Natural Sciences and Technology. His research focuses on molecular mechanisms of DNA repair, genomic instability in cancer, and applications of artificial intelligence in digital pathology. He has published extensively in high-impact journals such as Neuropathology and Applied Neurobiology , Diagnostic Pathology , and Nucleic Acids Research . Key research areas include the role of uracil-DNA glycosylases in DNA repair pathways, tumor-associated macrophage biology, and the development of machine learning tools for histopathological analysis. His work bridges molecular biology, clinical pathology, and computational methods, with recent studies investigating therapeutic effects on IBD-derived colonoids and T-cell dynamics in inflammatory bowel diseases. Dr. Pettersen collaborates with institutions like St. Olavs Hospital and SINTEF, emphasizing translational research in personalized medicine. He actively participates in academic outreach, delivering lectures on digital pathology, proteomics, and the societal impact of scientific advancements. His research has contributed to understanding genomic uracil’s role in lymphoma development and improving diagnostic accuracy through automated image analysis systems. Notable projects include developing the H2G-Net segmentation framework for gigapixel histopathology images and investigating the clinicopathological relevance of tumor-associated macrophages in meningiomas. His work highlights interdisciplinary approaches to address challenges in oncology, immunology, and medical technology.
