I am Professor at the Department of Biomedicine, University of Bergen, Norway and PI in the Metabolism and Cancer group. Our research aims to understand molecular interactions at the atomic level and the nuanced relationships between structure, dynamics and function of biomolecules. We develop and apply computational methods to simulate molecular motions, complementing experimental observations. Through collaboration with groups that develop the Amber software package for molecular simulations, we have developed the Amber force field to simulate molecular interactions of lipid complexes. With the Amber lipid force field, we are currently able to simulate complex molecular systems of any composition. We apply these methods to understand the function of large molecular systems based on intermolecular forces and inherent dynamics. Our force field development is also relevant to methods for virtual screening of compound databases against any macromolecular target and integrates well with the experimental screening of small compounds at the Department of Biomedicine. I am cofounder and shareholder of the company Pluvia Pharma AS, a startup biotech company in Bergen that seeks to develop small molecule pharmacological chaperones with potential to correct protein misfolding diseases.
I am member of the Program Commitee for medical education at UiB and responsible for the second semester of medical school. I teach subjects in biochemistry and cell biology for pharmacy, dentistry, and medical students and am also involved in teaching structural biology as part of master's and PhD courses at the Department of Biomedicine. I offer master's projects for students in pharmacy, nanoscience, biomedicine, and medical technology, as well as projects for the research program in medicine. Through the Federation of European Biochemical Societies (FEBS), I am involved in the development of biochemistry education and participate in FEBS forums as the Norwegian ambassador for biochemistry education.
When not teaching biochemistry I am very passionate about skiing and am part of the educational board of Snowsports Norway where I am involved in education and international certification of snowsport instructors.
