I am an Assistant Professor (RTD) in the Database Systems Research Group at the Faculty of Computer Science of the Free University of Bozen-Bolzano. I received a BSc degree in Applied Computer Science in 2008 and a MSc degree in Computer Science in 2010 from the Free University of Bozen-Bolzano. In 2014 I received a PhD degree (Dr. sc.) in Computer Science from the Department of Computer Science of the University of Zurich under the supervision of Prof. Michael Böhlen.
