Luca Gammaitoni (born 16 June 1961 in Perugia) is a scientist in the area of
noise
Noise is unwanted sound considered unpleasant, loud or disruptive to hearing. From a physics standpoint, there is no distinction between noise and desired sound, as both are vibrations through a medium, such as air or water. The difference arise ...
and
nonlinear dynamics. He is currently the Director of the Noise in Physical System Laboratory (NiPS Lab) at the Physics Department of the
Università di Perugia, in Italy.
Education and career
He graduated in physics at the
University of Perugia and obtained his Ph.D. in physics from the
University of Pisa in 1991 (S. Santucci advisor) with a thesis entitled "
Stochastic Resonance
Stochastic resonance (SR) is a phenomenon in which a signal that is normally too weak to be detected by a sensor, can be boosted by adding white noise to the signal, which contains a wide spectrum of frequencies. The frequencies in the white no ...
". He is currently Professor of Physics at the Faculty of Science of the
University of Perugia in Italy and the Director of The Noise in Physical Systems (NiPS) Laboratory.
NiPS, a research facility within the Physics Department of the
University of Perugia, has a long-standing tradition in studying physical systems in the presence of noise.
In 2004 he was awarded with the First prize for innovation ideas, Spin-off competition, of the
University of Perugia. Eventually, this led to the establishment of Wisepower srl. An innovative company devoted to the development of advanced technology in the field of self-powered wireless devices.
In 2016 he received the Special Breakthrough Prize in Fundamental Physics for the observation of gravitational waves, opening new horizons in astronomy and physics, as a member of the LIGO-Virgo collaboration.
In 2016-2019 he served as President of the Fondazione POST (Museo della Scienza di Perugia).
During the Covid-19 pandemics, together with Igor Neri, proposed a stochastic model for dealing with fluctuations in epidemic diffusion.
His scientific papers received more than 100.000 citations.
