About me

Dr. John Inge Johnsen received his PhD diploma at University of Tromsö, Norway under the supervision of Professor Terje Traavik in 1994. His thesis focused on the characterization of regulatory genetic elements in polyomaviruses and the effects these regulatory regions have on host/virus interaction.

After finishing his PhD, Dr. Johnsen went on to pursue his main scientific interest; cancer biology, oncogenes and tumor suppressor genes and 1995 he joined Professor Eric Stanbridge´s research group at University of California, Irvine where he studied the effects of p53 and genes regulated by p53 on cancer development.

After spending two years at the University of Tromsö as an assistant professor/lecturer Dr. Johnsen joined professor Per Kogner´s research group at Karolinska Institutet as a postdoctoral fellow where he together with Dr. Kogner built up the childhood neural tumor research consortium.

Dr. Johnsen became Associate professor at Karolinska Instituet in 2010. 








Research description

The main focus of our research group is to search for new treatment options that lead to better survival, less treatment-related complications and better quality of life for children with medulloblastoma and neuroblastoma. This is done by applying different Omic techniques to characterize the molecular landscape of malignant and corresponding non-cancerous cells within the tumor microenvironment and to use a translational approach applying preclinical in vivo models to characterize the anti-tumorigenic effects of drugs and compounds targeting specific biological aberrations in cancer cells or populations of cells located within the tumor microenvironment.
