- I was
born in Rome in 1954. I am married with one son. - I am a
Physicist. I am an expert in physical oceanography, dynamical systems theory
and theoretical climatology. EDUCATION - I received
my "Laurea" in Physics "Magna Cum
Laude" at the "La Sapienza" University of Rome on December
1977. - At that time a formal PhD did not exist yet
in the Italian University system (it was later introduced by the “Legge n. 28, 21/02/1980”; the first 3-year PhD cycle
started in 1984). The Laurea and a subsequent
research activity in Italy and/or abroad (supported mainly by the Consiglio Nazionale delle Ricerche - CNR) was the typical training of Italian
scientists. I carried out my post-Laurea research
activity at the Department of Physics of the “La Sapienza” University of Rome
and at the Department of Applied Mathematics and Theoretical Physics of the
University of Cambridge (UK), with support from the CNR. Professional
Experience - I
benefited from several research scholarships that allowed me to visit the
following Universities as a visiting scientist: ·
University of Cambridge
(Cambridge, UK) for 20 months (1981-82); ·
University of Florida
(Gainesville, FL, USA) for 6 months (1985-86); ·
Massachusetts Institute of
Technology - MIT (Cambridge-Boston, MA, USA) for 8 months (1987). - Later I
visited the following universities and research centres in the framework of
European Commission projects and for other projects: ·
CNRS (Grenoble, France) for
2 months (1997, 2019); ·
Hamburg University (Hamburg,
Germany) for 2 months (1998); ·
SINTEF (Trondheim, Norway)
for 2 months (2003, 2008); ·
Utrecht University (Utrecht,
The Netherlands) for 2 months (2007). ·
Institut Henri Poincaré (Paris, France) for 2 months (2019) - More recently I visited China (Qingdao), France (Paris), U.S.A. (Los
Angeles) and Hungary (Budapest) for other projects and collaborations. - I have
held the following positions at Italian Universities: ·
1984-1997: Ricercatore Universitario
(Tenured Assistant Professor) at the Istituto Universitario Navale of Naples
(Institute of Meteorology and Oceanography); ·
1997-2002: Associate
Professor at the University of L’Aquila (Department of Physics); ·
2002-2006: Associate
Professor at the University of Naples Parthenope (Department of Environmental
Sciences); ·
2006-present: Full Professor
at the University of Naples Parthenope (Department of Science and
Technology). Research
Interests - One of my main current research interests is the
application of concepts and methods of nonautonomous dynamical systems to
some relevant aspects of climate dynamics. More specifically, I am studying
the pullback attractors of nonautonomous chaotic nonlinear dynamical systems
and the role the knowledge of such time-dependent attractors may play in
improving our understanding of the system’s intrinsic variability. The
nonlinear mathematical tools used in the numerical analyses include both
low-dimensional systems of coupled ordinary differential equations and the
partial differential equations describing the fluid motion of large-scale
oceans in a rotating reference frame. - My most recent research interest concerns the dynamical
systems characterization of the link between orbital forcing and glacial
terminations implied by the Milankovitch hypothesis. To this respect, a
dynamical systems paradigm, denoted deterministic excitation, has been
proposed and applied to the late Pleistocene ice age. - In recent years I have also conducted process-oriented
modeling studies on nonlinear western boundary currents -and on the intrinsic
low-frequency variability of their extensions- through both a hierarchy of
mathematical models (ranging from low-order models to the primitive equations
of geophysical fluid dynamics) and laboratory experiments with rotating
platforms. I have paid particular attention to the Kuroshio Extension and the
Gulf Stream. The analyses are based on geophysical fluid dynamics and
nonlinear dynamical systems theory, are validated through altimetric data and
are carried out in the general context of climate dynamics. - Other model studies concern the Antarctic Circumpolar
Current (and, more in general, the Southern Ocean) and the coastal
circulation in the Southern Tyrrhenian Sea, with particular attention to the Campania Coastal System and the Gulf
of Naples. - Other less recent
researches concerned (i) linear aspects of the wind-driven ocean circulation,
including Rossby wave propagation; (ii) regional and coastal oceanographic
modelling; (iii) nonlinear and dispersive long wave modelling based on the
Kadomtsev–Petviashvili (KP) equation; (iv) nonlinear stability analysis of
geophysical flows. Funding - Role in projects funded by the European Commission: ·
