Dr. Nunes-Xavier is an experimental biologist and cancer researcher that initiated her career at the University of Oslo, where she obtained a Bachelor Degree in Natural Sciences (2005) and a Master Degree in Molecular Biology (2006). During the Master Degree, she made a mobility stay, within the Erasmus program, to the University of Valencia (Spain), where she obtained an additional Master Degree in Molecular Biology (2007). Afterwards she was awarded with a Marie Skłodowska-Curie Fellowship to perform her PhD (2007-2011), as part of a European Research Network training program, and obtained her European PhD at the University of Valencia (Spain) in 2011. During her PhD period she performed secondments at Karolinska Institute in Sweden and Weizmann Institute in Israel. Dr. Nunes-Xavier started as a postdoc at Oslo University Hospital in 2013 with a fellowship from the Norwegian Cancer Society. Since 2015 Dr. Nunes-Xavier has been a Principal Investigator and a holder of a FRIPRO mobility grant from The Research Council of Norway, co-funded by Marie Skłodowska-Curie Actions.

Dr. Nunes-Xavier main research line is to define novel targets in cancer treatment, with a focus on immune checkpoint proteins and protein tyrosine phosphatases. The pursued goals will have an important clinical translation to overcome or prevent cancer disease progression and current resistance to therapy.
