Research homepage of Samuli Siltanen

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, dynamic X-ray tomography, discretization-invariant Bayesian inversion, and the Novikov-Veselov equation.

I work as Professor of Industrial Mathematics at the Department of Mathematics and Statistics of University of Helsinki and as team leader in the Finnish Center of Excellence in Inverse Problems Research.

The picture above shows an X-ray measurement of a walnut (middle) and a tomographic reconstruction of a slice through the walnut (right).

I have written a textbook on inverse problems with Professor Jennifer Mueller (Colorado State University). The book is available for ordering at the SIAM bookstore. For computational resources (Matlab files) related to the book, see this page.

Here are a couple of my old info pages:

  • My old electrical impedance tomography page
  • My old low-dose three-dimensional X-ray imaging page

    Here are links to some non-scientific stuff I love to create.
