I am a postdoctoral researcher and holder of the Research Fellowship ''2020 researchers: Train to Move'' at the University of Turin, Italy. My main research interest is descriptive set theory and its connections with other areas of mathematics.
The reason why my given name is spelled "Vassilios" instead of "Vassilis" in my CV and publications.
