He graduated from the Faculty of Physics at the Sofia University(1969)
He defended doctoral dissertation (1979) and dissertation for Doctor of Physical Sciences (1999), approved for Doctor of Physical Sciences on 04.06.2001
Research
He worked in the field of growth and study of the properties of crystals (ferroelectrics), optical properties of photorefractive crystals of oxide compounds
He created equipment and technology for crystal growth using various methods (Czochlarski's with weight control of the crystal diameter, Bridgman's, growth from a gas phase with temperature oscillation)
Over 70 new types of crystals have been created in the crystal growth laboratory (semiconductor, complex oxide crystals, ferroelectric, manganate, etc.)
A technology has been created for growing crystals for infrared light receivers from 3 to 5 microns for night surveillance with an economic effect of 850,000 leva
Crystals for uncooled nuclear radiation detectors worth $20,000 were created for the American company Targetinstruments
Prof. Marin Gospodinov headed the scientific and applied project Zikatel at the Ministry of Defense
The technological control systems created in the laboratory have been implemented in several glass factories in the country with an economic effect of 400,000 leva
