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.
