Professor Claes Ohlsson receives an additional SEK 15 million over five years within the Wallenberg Clinical Scholar program, following an evaluation by the Knut and Alice Wallenberg Foundation. Up to 60 percent of those who were originally named Wallenberg Clinical Scholars receive an extension. Together with his colleagues at Sahlgrenska Osteoporosis Center, Claes Ohlsson conducts completely unique research on osteoporosis and bone fractures. In collaboration with other researchers, he has discovered how genetics, environmental factors and the body’s bacterial flora together affect bone mass and the risk of suffering a fracture. The knowledge can lead to biomarkers to identify patients who are at high risk of fractures as well as drug targets for fractures.
