Curriculum Vitae
Giancarlo C. Righini studied at
the
University
of Firenze and received the "laurea" (dr. degree) in Physics in
1967.
In
1968 he was awarded the title of chartered teacher of
mathematics and
physics.
After having been research fellow at
the
Institute of Physics of the University of Firenze from 1968 to
1971 and
having served in Technical Corps of the Army, since 1972 he is
in the
staff of the Research Institute on Electromagnetic Waves (IROE),
now
"Nello Carrara" Institute
of Applied Physics (IFAC), of the National Research
Council of
Italy
(CNR).
In 1988 he was appointed to the
position of
Senior
Researcher, and since 1991 he is one of CNR Research Directors.
He was member of IROE Scientific
Committee in
the
years 1973 to 1981; from 1983 to 1996 he was Director of the
National
Group
on Quantum Electronics and Plasma Physics (GNEQP-CNR).
From 2006 to 2009 he has been Director
of the
CNR Department of Materials and Devices.
At IFAC he leads the research group at
MDF Lab (Photonic Materials and Devices). His present research
interests concern
microresonators, grating structures, integrated optics, glasses
for
optoelectronics,
nonlinear optics. Experimental activities carried
out in the laboratory include fabrication of waveguides and
components
in
glass by ion exchange, thin-film deposition and etching, and
optical
characterization
of thin films by guided-wave techniques.
He has published over 400 papers (many of them also on
holography
and
optical signal processing), and is co-author of 6 international
Patents. He
has presented several invited papers at international
Conferences. He
has
authored (or co-authored) various chapters in books on
optoelectronics
and
guided-wave optics (both in Italian and in English).
He has been chairman or co-chairman of many National and International Conferences, and has edited several Proceedings Volumes.
Prof. Righini has regularly taught
monographical courses at different Universities in Italy. From
1994 to
2004 he
was contract Professor of Optical Technologies at the
Specialization
School in Optics of the University of Firenze, and regularly
lectures
at the Engineering Faculty, Università di Firenze.
For
many years
he also was in the Academic Staff of the
Advanced Course in Optical Technologies at AILUN in Sardinia.
Since
2005 he is contract professor of Optoelectronics at the Sciences
Faculty, Università di Florence.
He has been supervisor of many thesis works
of
graduate
and PhD students in Physics and Electronic Engineering, at the
Università di Firenze, as well as member of the Jury in
several
PhD defenses in
France
and Spain.
He has been responsible of several bilateral cooperation
Projects (with Czech Republic, France, Great Britain, Hungary,
Portugal, Spain, and
United States) in the area of guided-wave optics. He has been
involved
in
two ESPRIT Projects and one ACTS Project of the European
Commission, as
well
as in many National Projects funded by CNR or by the Ministry of
Education,
University and Research (MIUR).
