I am a Finnish mathematician mainly interested in inverse problems of medical imaging. The goal of my scientific work is to design efficient numerical methods that have a sound mathematical basis and solve real-world problems. I have published research articles mostly about the following topics: Electrical Impedance Tomography (EIT), low-dose three-dimensional X-ray imaging, discretization-invariant Bayesian inversion, and the Novikov-Veselov equation.

For examples of inverse problems and my research about them, please see my Inverse Problems Examples Page:

I have written a textbook on inverse problems with Jennifer Mueller:

.

The book is available for ordering at the SIAM bookstore.

For computational resources (Matlab files) related to the book, see this page.

I work as Professor of Industrial Mathematics at the

Department of Mathematics and Statistics
of University of Helsinki

and as senior scientist in the
Finnish Center of Excellence in Inverse Problems Research.
