    Research interests

    My research revolves around statistical approaches to image analysis and machine learning. Specifically, I have published in topics of multiplicity, divergence functions, and multi-instance learning. I am currently engaged in three larger projects:
    Machine learning approaches to histopathological image analysis, which is a main focus of the Computational Pathology research group. The research group matches statistics and computer science with pathology and oncology. I jointly supervise three PhD students in this group.
    Statistical methods in ocean surveying, in the ICT+ project " Transforming ocean surveying by the power of DL and statistical methods".
    Integrative multi-omics analysis as part of the Systems Epidemiology research group. This includes the supervision of one PhD student.
    I engage in teaching, and research about teaching as a member of the research group Realfagsdidaktikk i høyere utdanning (Mathematics and Science Didactics in Higher Education), and various forms of outreach and dissemination.
    Other interests are gender diversity in STEM and data sharing.
