Research
Erik’s research is focused on using statistical learning techniques for Xray and neutron diffraction, and the development of software packages that make such functionalities available to a wide user base. In this project he is closely working with researchers at the Data Management and Software Center of the European Spallation Source (DMSCESS) in Copenhagen and the MAXIV facility near Lund.
