Per Christian Hansen is a VILLUM Investogator and his research focuses on computational methods for the solution of large mathematical and engineering problems. His main research area concerns the numerical solution of inverse problems in, e.g., tomography and iamge deblurring. His work on numerical methods for regularization is internationally recognized. His h-index is 48 (March 2019) and he is a SIAM Fellow.

Per Christian Hansen is professor of Scientific Computing at the Department of Informatics and Mathematical Modelling. He was awarded the Danish Dr. Techn. doctoral degree in 1996 from DTU in the area of numerical analysis. He has spent several research visits at American universitise, such as Stanford University, UCLA, Emory University, and Tufts University.

Per Christian Hansen teaching in numerical algorithms and inverse problems.  He has published 4 books on numerical methods and inverse problems and more than 100 scientific papers in international journals.

Expertise

Professor Per Christian Hansen has worked with numerical regularization algorithms for 30 years, has published 4 books and 100+ papers in leading journals, and his research monograph ``Rank-Deficient and Discrete Ill-Posed Problems'' is the most widely used book on the subject. He has developed several related software packages, of which "Regularization Tools" has become astandard toolbox for analysis and solution of discrete inverse problems.

His current research projects involve inverse problems and image deblurring (joint with University of Bath, Emory University, Atlanta and Tufts University, Boston), tomography in material science (joint with Manchester University and Linköping University), and computational uncertainty quantification.
