I am an Associate Professor of Imaging Instrumentation and Detection Technologies at Turku PET Centre, University of Turku. My current research interests are medical imaging: imaging instrumentation, detector technologies and AI in imaging. I am also interested in longitudinal machine learning, geometric function theory, especially hyperbolic type geometries, and pedagogics.
