I'm a research assistant and doctoral student at the University of Zurich in the Database Technology Research Group, working on my doctoral thesis under the supervision of Prof. Michael Böhlen. 

I received my Bachelor's and Master's degree in Computer Science in 2013 and 2015, respectively, from the Free University of Bolzano. In the fall of 2015 I started my PhD.
