Research

PhD candidate at Western Norway University of Applied Sciences, Department of Computer science, Electrical engineering and Mathematical sciences and Mohn Medical Imaging and Visualization Center, Department of Radiology, Haukeland University Hospital. My research activities are mainly related to machine learning and medical image analysis, with a particular focus on design methodologies in deep learning for efficient use of data.
