About me

I am a research fellow at San Raffaele Scientific Institute (Milan, Italy).

I hold a Ph.D. in Computer Science and Engineering from Politecnico di Milano, with a thesis entitled "Achieving quality in crowdsourcing through task design and assignment". Before that, I received my B.Sc. and M.Sc. in Computer Engineering from Politecnico di Milano, both with a final grade of summa cum laude. In my spare time I enjoy playing the drums, which I have been doing for the last fifteen years or so.

From 2011 to 2016, I served as a teaching assistant at Politecnico di Milano in the following topics:

  • Mobile applications: introduction to Android development (slides here)
  • Computer science principles: principles of programming in C++11 (slides here)
  • Advanced Web technologies: how to build Web applications using Spring, JSTL and JPA (slides here)
  • Digitial image processing: introduction to digital image processing and shape extraction


My curriculum vitae et studiorum is available here.
