Gunnar’s research contributes to science-based innovation in the development of research policy, evaluation, and funding, and in the use of aggregate indicators for the same purposes. He created the “Norwegian Model” for a complete representation of scientific publications from all fields of research and contributed to the design of general indicators for measuring scientific collaboration at various levels of aggregation. He has developed a large network of research collaboration with co-authors in twenty-four countries.
