Higher education and employment history
My education is from University of Oslo, with a master in cell biology (1997) and a PhD (dr. scient.) degree in cellular immunology. I worked for three years as a post. doc. at Institute of Cancer Research, the Radium Hospital in the lab of Professor Kirsten Sandvig, and then for 2 years as a scientific assistant in the lab of Professor Oddmund Bakke at Department of Molecular Biosciences, University of Oslo. June 2008 I started a new post. doc. period, financed by the Norwegian Research Council, as a group leader. I am still attached to Oddmund Bakkes group, where I tutor PhD and master students.
Appointments
- Member of the board of the Norwegian Immunological Society 2007-2008
- Secretary of the Norwegian Immunological Society 2008-2009
Collaborations
Since our group is a member of Centre for Immune Regulation (CIR) I have various internal collaborations, e.g. with Jan Terje Andersen in the group of Inger Sandlie, looking at intracellular trafficking of the neonatal Fc receptor. Outside CIR i collaborate with Vibeke Gjerstad in the group of Anne Spurkland, mapping the subcellular localization of signal molecules involved in T-cell signalling and migration. I also collaborate with the group of Johanna Olweus at Institute of Cancer Research, the Radium Hospital, working on immune therapy and antigen presentation. Recently I started a collaboration with Unni Grimholt and Kjetill Jakobsen, CEES (Centre for Ecological and Evolutionary Synthesis), where mapping of the immune system of fish (cod and salmon) is a central topic.
