Job description

I am the Director of Visual Intelligence. This is a Centre for Research-based Innovation (SFI) funded by the Research Council of Norway and a consortium of private and public partners. We are at the international forefront in deep learning research for complex image analysis.

I am co-Director of Integreat. This is a Centre of Excellence (SFF) funded by the Research Council of Norway and the university partners, the University of Oslo and UiT The Arctic University of Norway. We are at the international forefront in knowledge-based machine learning.

My main position is as Professor in the UiT Machine Learning Group.

I am also an Adjunct Professor at Pioneer Centre for AI, University of Copenhagen & Norwegian Computing Center.

I Wish to Contribute to our joint Future through Research

My motivation is to contribute the foundational research needed to advance artificial intelligence by exploiting context for better understanding of the world and to develop AI seen in the context of society, the sciences, and to help solve important societal challenges in a human-centered way leading to new innovations. I have extensive collaboration with industry and public sector stakeholders. My methodological research has focused on topics such as neural networks, information theoretic learning, kernel methods, unsupervised learning, self-supervised learning, and explainable AI (XAI). My research is regularly published in the most prestigious conferences and journals in the field (ICLR, ICML, NeurIPS, etc). I have been fortunate to work with many good colleagues and together our research has been recognized by our peers in the field:
