Image analysis is one of my main areas of interest. My PhD thesis is on "Mathematical methods of spectral X-ray computed tomography data processing", which I am working on at the Department of Mathematics, Faculty of Mechanical Engineering, Brno University of Technology. The research of new mathematical methods is carried out in cooperation with the CTlab CEITEC, which is also under the BUT. My main focus is on dual target acquisition, which can be used to obtain spectral information about samples and, based on this, the position of individual materials in a volume can be mapped. This is a multidisciplinary problem where physics, chemistry and mathematics are combined.
