Since 1984 and until now, Riccardo Barbieri has been the professor of theoretical physics at Pisa, first at the University of Pisa (1984–97), and then at the Scuola Normale Superiore (1998–present). Some of his most influential results in this period include:
* In 1988, the quantitative formulation of the naturalness concept in supersymmetric models.
* In 1990, the formulation of a reference parametrization of the quantum corrections to the electroweak precision observables.
* In 1995, pointing out the significance of flavour and CP violations in supersymmetric unified theories even in the absence of any flavour or CP violation in the input for the soft-supersymmetry breaking parameters.
* In 2006, the proposal of a Dark Matter model based on a second Higgs doublet without vacuum expectation value.
Mentoring
Having taught in Pisa for 30 years, Riccardo Barbieri is acclaimed for creating a numerous and flourishing school of theoretical high-energy physics. Among many of his students and postdocs who went on to become professors of theoretical physics in Italy and around the world, are
Gian F. Giudice, and
Michelangelo Mangano (permanent staff members at the CERN), Giovanni Ridolfi (professor at Universita' di Genova),

Famous quotes
“''Elementary particle physics is the quadrant of nature whose laws can be written in a few lines with absolute precision and the greatest empirical adequacy.''”
Awards and honours
Prof. Barbieri was awarded the "Ordine del Cherubino" from the University of Pisa in 1997, the Humboldt Prize and, more recently, the Physics Prize of "Accademia Nazionale dei Lincei" in 2017. He was also a Miller Visiting Professor at the University of California, Berkeley.
