About Oscar Jalnefjord

Oscar Jalnefjord is an associate professor at the Department of Medical Radiation Sciences at University of Gothenburg and a senior medical physicist at the Department of Biomedical Engineering and Medical Physics at Sahlgrenska University Hospital. He received his PhD in Magnetic Resonance Imaging (MRI) in 2018 and has since combined clinical work with research focusing on development of novel MRI methods for characterizing microvasculature and microstructure in tumors.
