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.
In 2006 he has been appointed Director of the
newly established National Department
on Materials and Devices.
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).
At IFAC he was head of the
Optoelectronics and Photonics Dept. and he led the research group on
Optoelectronic Technologies. His recent research interests have
concerned
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 350 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. Since 2004 he
is contract Professor of Optoelectronics at the Physics Department,
University of Florence. From 1994 to 2004 he has been contract
Professor of Optical Technologies at the Specialization School in
Optics of the University of Firenze, andhe regularly lectures at
the Engineering Faculty, University of Firenze. For many years he
also was in the Academic Staff of the
Advanced Course in Optical Technologies at AILUN in Sardinia.
He has been supervisor of many thesis works of
graduate
and PhD students in Physics and Electronic Engineering, at the
University
of Firenze, as well as member of the Jury in several PhD defenses in
France
and Spain.
He has been responsible of several bilateral cooperation
Pro-jects (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).
