Giovanni Villadoro

Giovanni Villadoro is a theoretical physicist interested in the theory and the phenomenology of fundamental interactions.

Giovanni Villadoro got his MSc degree in physics at the Univ. La Sapienza of Rome in 2002, with supervisor G. Martinelli. He got his PhD degree at Univ. La Sapienza of Rome in 2006, with supervisor F. Zwirner. He was a postdoctoral fellow at Harvard University from 2005 to 2008, at CERN from 2008 to 2010 and at SLAC, Stanford from 2010 to 2013. Since 2013 he is a permanent scientific staff at ICTP.

Villadoro was awarded the 2006 Fubini prize and the 2007 Gamberini prize.

Villadoro's research activity spanned different areas of the physics of fundamental interactions, including: high energy phenomenology beyond the Standard Model, dark matter, flavor physics, Higgs physics, supersymmetry, string theory compactifications, quantum field theory, cosmology. Recently his efforts have been focusing mostly on various aspects of QCD axion phenomenology.
