Oddvar Oppegaard is senior physician at the Department of Infectious Diseases, Haukeland University Hospital and an assistant professor at the Department of Clinical Science, UoB. Important fields of research have been serious streptococcal infections with the main focus on bacterial virulence, resistance and pathogenesis. The work includes bioinformatic whole genome analysis, as well as genetic characterization and manipulation of bacterial strains in the laboratory. Oppegaard and the streptococcus research group at the University of Bergen and Haukeland University Hospital are currently participating in the PERMIT and PERAID projects (https://permedinfect.com/) funded by Nordforsk and the EU. These projects aim to promote research into personalized medicine (PM) in serious infectious diseases, especially life-threatening necrotizing soft tissue infections (NSTI) and sepsis.
