In the years 1954–66 he was associated with the Institute of Radio Engineering and Electronics of the Academy of Sciences of the USSR. In 1966 he became director of the Institute of Information Transmission Problems of the Academy of Sciences of the USSR.
Siforov’s main works have been devoted to theoretical questions on the stability of resonant amplifiers, the detection of signals and frequency conversion, radio reception at microwave frequencies, pulse radio communications, and radio navigation. He has also been concerned with the theory of information transmission and with methods of detecting radar signals and controlling radio interference.
In 1954, Siforov became chairman of the Central Board of the A. S. Popov Scientific and Technical Society for Radio Engineering, Electronics, and Communications. He is an honorary member of the Hungarian Academy of Sciences (1973) and has been awarded two Orders of Lenin, five other orders, and various medals.
