Oleg G. Morozov is full professor of Kazan National Research Technical University n.a. Andrey Tupolev (KNRTU-KAI), Head of Radiophotonics and Microwave Technologies Department, and Director of R&D Institute of Applied Electrodynamics, Photonics and Living Systems. He leads research on microwave photonics, fiber optic sensors and communications, and transfer of optical methods into microwave sensors and technologies. He has

over 100 papers and 10 monographs concerning the principles of tandem amplitude-phase modulation of microwave and optical carriers, and its application in the wide spectrum of technical and living systems. Over the past five years, his interests have been in the field of quantum communications, in particular, the quantum key distribution of frequency-coded subcarriers. Research in this area is carried out jointly with the Kazan Quantum Center of KNRTU-KAI. Oleg G. Morozov is an Honorary Worker of Higher Education, Fellow of the International Academy of Telecommunications, Senior Member of OSA and SPIE, and regular member of the Optical Society n.a. Rojdestvenskiy (ROS), EOS, and IEEE.
