The University of Tromsø is the largest research and educational institution in northern Norway. The University's location makes it a natural venue for the development of studies of the region's natural environment, culture, and society. The main focus of the University's activities is on the Auroral light research, Space science, Fishery science, Biotechnology, Linguistics, Multicultural societies, Saami culture, Telemedicine, epidemiology and a wide spectrum of Arctic research projects. The close vicinity of the Norwegian Polar Institute, the Norwegian Institute of Marine Research and the Polar Environmental Centre gives Tromsø added weight and importance as an international centre for Arctic research. Research activities, however, are not limited to Arctic studies. The University researchers work within a broad range of subjects and are recognised both nationally and internationally. On January 1, 2009 the University of Tromsø merged with Tromsø University College. On August 1, 2013 the university merged with Finnmark University College to form Universitetet i Tromsø – Norges arktiske universitet (The University of Tromsø – The Arctic University of Norway), thereby adding campuses in Alta, Hammerfest and Kirkenes.
