Principal Investigator at the Institute of Experimental Pathology, University of Iceland, Keldur
1974: B.Sc. in Biology, University of Iceland 1994: M.Sc. Health Sciences, Faculty of Medicine, University of Iceland
Research interests: Fish diseases and immunology
Education: at University of Iceland. 1974, B.Sc. in biology. 1976, B.Sc. (120e), a research project on viral antibodies in Multiple sclerosis. 1994, M.Sc. in health sciences, studies on the immune system of Atlantic salmon.
The institute: Institute for Experimental Pathology at Keldur is the only institute in Iceland doing research, screening and diagnosis on diseases in animals, i.e. mammals, birds, fish and shellfish. Since it´s foundation, in 1948, Keldur has been affiliated to the University of Iceland through the Medical department. Sigrídur has worked as a specialist at the Department of Fish Diseases since 1987, doing research, screening and diagnostic work.
Research: As regards fish diseases, the main research has been on Renibacterium salmoninarum, a bacterium that infects salmonids only, both in their fresh water and marine phases. In current projects on Renibacterium my coworkers at Keldur are Ívar Örn Árnason and Árni Kristmundsson. Further, I have collaborated with colleagues at Keldur and elsewhere in research on diseases in marine fish and vaccination against bacterial diseases. I have also made immunological studies of salmonids as well as marine fish, mainly cod.
Supervising: SG has been the spuervisor of two M.Sc. students, served in one doctoral committee and been appointed opponent in a few M.Sc. and Ph.D. projects.
