The PhD was received in 2003, under the supervision of Professor Arne Holmgren at Karolinska Institutet and was focused on biochemically characterizing the thiol redox regulating glutaredoxin system in depth in E. coli. She moved to the Karolinska University Hospital at the Division of Pathology, to work on redox regulation of human cancers with special emphasis on Se metabolism. She became associate professor in 2009 in experimental pathology and appointed senior lecturer in 2010. In 2014 she moved to the Department of Medical Biochemistry and Biophysics at Karolinska Institutet, were she established her own research group, focusing on more mechanistically directed studies with the aim to characterize novel Selenium compounds and Selenium nanoparticles as anticancer agents.
