Per Christian Hansen's research focuses on computational methods for the solution of inverse problems in, e.g., tomography and image deblurring. His reseach also involves computational methods for uncertainty quantification and error propagation in inverse problems. His h-index is 58 (2026) and he is a SIAM Fellow. Per Christian Hansen is professor of Scientific Computing at the Department of Informatics and Mathematical Modelling (DTU Compute). He was awarded the Danish Dr. Techn. doctoral degree (habilitation) in 1996 from DTU in the area of numerical analysis. He has spent several research visits abroad at Stanford University, UCLA, Emory University, and Tufts University in USA as well as National Inst. of Informatics in Tokyo. Per Christian Hansen teaches numerical methods and inverse problems. He has authored/coauthored 6 books on numerical methods and inverse problems and 130 scientific papers in international journals.
