Starting from 1991 he worked as a scientist in USA, Finland, Spain, Germany and in 1993 he was invited to the Optical Sciences Centre of Australia and later founded his own laboratory Nonlinear Physics Centre of
ANU. Starting from 2000 Yuri Kivshar worked in different fields of
nonlinear optics and carried out research of
solitons and
metamaterials, nonlinear
photonic crystal and composite materials theories. He made fundamental impact into
self-focusing effect,
metamaterials,
dielectric nanoantennas,
topological insulators, optic signal processing and optic communications. He also discovered series of
solitons and described their properties. In 2010 Yuri Kivshar was invited to St. Petersburg, Russia in terms of government Megagrant program. He became a scientific leader of the International Research Centre for Nanophotonics and Metamaterials of the
ITMO University (Saint-Petersburg, Russia). ==Publications==
