Personal Profile 

I did my undergraduate degree in Biomedical Laboratory Science at the Karolinska Institute in Sweden. Following this I acquired a PhD in Molecular Virology at the University of Edinburgh. Since then I have been working as a postdoc in the Michlewski group.



I currently work on the E3 ubiquitin ligase Trim25, a novel RNA binding protein, that has an important role in innate immunity. I am exploring the functional importance of its RNA binding ability in cell biology and during viral infection.
