About me
I am a Machine Learning Scientist at
Amazon in Berlin (Germany).
Before joining Amazon I have been PhD Student in Applied Mathematics ("MASSC"), at University of Milan (Italy) under the supervision of
Prof. Nicolò Cesa-Bianchi.
During my PhD I also had the the opportunity to collaborate closely with
Prof. Claudio Gentile and
Fabio Vitale.
Something that you cannot find on
my LinkedIn profile: some my jokes have been selected for
this book.
