Theoretical and experimental investigation of fundamental characteristics of turbulence, with special emphasis to Magnetohydrodynamic (MHD) turbulence, and applications to low-frequency fluctuations as observed both in the Solar Wind and in Laboratory plasmas. Data used comes from Helios II and Ulysses satellites, and from a toroidal plasma device in Reversed Field Pinch configuration (RFX in Padua, Italy).

Main results:

1. Study of shell models for MHD turbulence;
2. Study of the coalescence as final fate of non linear tearing instabilities;
3. Investigation of intermittency in MHD turbulence, anomalous scalings.

Investigation of characteristics of physical processes which happens on the solar photosphere and in the solar corona. In particular studies use dataset from the franco-italian telescope THEMIS and data coming from different solar telescopes, as the solar telescope at the Nauchny Observatory (Crimea, Ukraina) and the Big Bear Solar Observatory (USA).

Main results:

1. Modelling turbulence in solar surges;
2. Analysis of scaling laws of solar granulation;
3. Study of scaling laws of current helicity in active regions of the sun;
4. Investigation of statistical properties of solar flares.

Dynamical properties of liquid crystals have been investigated, when external stresses are applied to these anisotropic media.

Main results:

1. Study of the chaotic behaviour in molecular reorientation, and characterization of the way to chaos through a cascade of gluig bifurcations;
2. Investigate spatio-temporal intermittency in electrohydrodynamic turbulence;
3. Diffusion of powder in liquid crystals under turbulent conditions.

Investigation of the characteristics of absorbition lines Ly-apha in Quasars spectra, and study of statistical properties of the Universe on large scales.

Main results:

1. Multifractal properties of Ly-alpha forests associated to Quasars;
2. Evolution in redshift of characteristics of Ly-alpha clouds.

Physics of Sport is a new approach for physicists to human performances. Athletic World records are considered as up to date experimental results.

Main results:

1. Characterization of different scaling laws in running and swimming, related to aerobic and anaerobic energy expenditure of athlets;
2. Statistical analysis of the whole Athletic hystory on the basis of World records.
