Campus Porsgrunn (K-138B)
I am professor with responsibility for microbiology, epidemiology, and infectious disease control at USN. I have a background as Mphil. in Medical Biology from the University of Tromsø, did my PhD in infectious disease epidemiology at the University of Copenhagen, followed by a postdoc position in microRNA research at NTNU and researcher in high consequence pathogens at NTNU. Since 2015 I am employed at the University of South-Eastern Norway.



Emanating from the 1978 Declaration of Alma Ata, Article VII (4): 
(Primary Health Care) involves, in addition to the health sector, all related sectors and aspects of national and community development, in particular agriculture, animal husbandry, food, industry, education, housing, public works, communications and other sectors; and demands the coordinated efforts of all those sectors;….
To highlight and to demonstrate the importance and the essential requirement for intersectoral coordination and collaboration to achieve the goals of Alma Ata and the “Health for all”-movement is my personal professional goal. 
To reach this goal I wish to bring together Primary Health Care with the OneHealth initiative. The One Health concept recognises the necessity of close collaboration and communication between the various disciplines of human and veterinary medicine, along with associated allied health scientists, and represents a powerful facilitating strategy for “Health for all”, both in the Southern and Northern hemisphere. Among others, nurses, physicians, veterinarians, environmental scientists, public health professionals, wildlife experts and plant pathologists working together will offer extraordinary synergistic advantages whether the health challenges result from emerging infectious diseases, antibiotic resistance, non-communicable disease, nutrition, food safety, natural disasters or climate change. Subsequently, the findings of such collaborations must then be translated to the common people, so that professional results can be applied by the people for improving their own and their communities health.
