NIKOLAY KIROV NIKOLOV
(22.10.1943 – 20.03.2013)
Nikolay Kirov was born in Gorna Oryahovitsa.
He studied english secondary school in Sofia and chemistry in the Sofia University.
Nikolay Kirov defended PhD in the ISSP – BAS (1973) and ScD (1988).
The area of his investigations was molecular spectroscopy.
He was head of the Laboratory of Optics and Spectroscopy at the ISSP – BAS (1986–2002).
Nikolay Kirov was director of the Institute of Solid State Physics – BAS (1991–1999).
He was one of the creators of the Internationa school of Condense matter physics hold in Varna every even years since 1980.
He lectured cours “Molecular Spectroscopy in condense matter physics” in Parma, Italy (1983–1985).
The second cours was “New lines in optic spectroscopy of condense matter”, University of Calabria, Cosenza, Italy (1986–1988).
