Something about me (you never know what people are curious of)
I got my degree in Mathematics in Rome, la Sapienza in 1993, spending my fourth year in Utrecht (NL) as an Erasmus exchange student. My thesis was on coalgebras over the ring of integers. Then I participated in the Master Class on Algebraic Lie Theory and Hypergeometric Functions in the Netherlands, where I also received my PhD in 1999 studying a quantum analogue of Fourier transform. My final advisor was Tom Koornwinder. At the same time I did volunteer work for the Tussenvoorziening and had related training. After spending a few months at Cergy-Pontoise and Paris VI, I moved to Antwerp where I learnt about the Brauer group of Hopf algebras and of braided categories. Shortly after I moved back to Rome, Tor Vergata and in 2001, to Padova where I am associate professor in Algebra since october 2015. At present I mainly work on algebraic and geometric properties of conjugacy classes in reductive algebraic groups (key example GL(V)) with some digressions in finite groups of Lie type, and an eye to applications in Hopf algebra theory and Representation Theory. At the moment I have collaborations with mathematicians in Córdoba and La Plata, Argentina, in Erlangen, in Rome and of course in Padova. In 2014 I have obtained Abilitazione for full professoship.
