CV for Per Christian Hansen

I have worked with numerical regularization algorithms for 30 years,
have published 100+ papers in leading journals, and my books on numerical methods
for inverse problems are widely used.
I have also developed several related software packages, of which
Regularization Tools
is a popular toolbox for analysis and solution of discrete inverse problems.
More recent packages area
AIR Tools II
with algebraic iterative reonstruction methods, and
IR Tools
with iterative regularization methods and test problems.
My hindex is 48 according to Google Scholar (March 2019) and I am a SIAM Fellow.

Specialization.
Numerical analysis. Algorithms for inverse problems, imaging, and tomography.
Matrix computations and iterative regularization algorithms.
Subspace methods in regularization and signal processing.
Highperformance scientific computing.
Computational uncertainty quantification.
Current Research Collagorations
Computational methods for inverse problems in physics
(joint with DTU Physics) and antenna measurement (joint with TICRA).
Iterative image deblurring and image reconstruction (joint with
University of Bath, Emory University, Tufts University, and
Linköping University).
Uncertainty quantification for inverse problems (joint with University of Montana).
