Per Christian Hansen's 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. He is one of the two Danish mathematicians who are Highly Cited, and his h-index is 38 (June 2013).

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, and Emory 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 80 scientific papers in international journals.

Expertise

Professor Per Christian Hansen has worked with numerical regularization algorithms for 25 years, has published 3 books and 80+ 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 the standard toolbox for analysis and solution of discrete inverse problems, and it has been downloaded more than 4000 times from Matlab's File Exchange Central.

His current research projects involve geomagnetic prospecting (joint with University of Naples, Italy), image deblurring (joint with Emory University, Atlanta, USA and Tufts University, Boston, USA), tomography in material science (joint with Risø National Laboratory and Linköping University), and scientific GPU computing.
