I earned my PhD at the University of Bergen on organoid models and novel biomarkers for improved treatment of endometrial cancer. I am currently a postdoctoral fellow in the Bergen Gynecological Research Group, where my main focus is to study drug resistance and identify new treatment strategies for endometrial cancer patients. Currently, I am working on a study that applies advanced functional genomics to identify genes responsible for carboplatin resistance. This new knowledge will be used to find novel treatments for chemotherapy resistant endometrial cancers.
