Bakhtiyor Baizakovich Baizakov, a Head of laboratory at the “Physics-Sun” Physical-Technical institute of the  Academy of Sciences of Uzbekistan.
He was born on February 25, 1954 in Samarkand region.
He studied at the faculty of Physics of the Tashkent State University (now NUUz) and graduated in 1977 with speciality of theoretical physics. In the same year he started working at the PTI of UzAS. During his career, he worked as an engineer, leading engineer, researcher and senior researcher. In 2000, he defended his PhD degree at the physics department of the NUUz with speciality “04.01.02 - Theoretical Physics” on topic “The dynamics of optical solitons in heterogeneous media and their borders”. Since January 2003, he has been working as a senior researcher at the laboratory of “Theory of solid state and semiconductors” at the PTI. In 2013, he was appointed as a Head of the laboratory.

The scientific activity of B. B. Baizakov began with the study of the dynamics of charge carriers in semiconductor detectors. He published a number of articles on this topic in the period 1980-1986 years in republican and international journals. In 1987–1994, he studied the technology and physics of the synthesis of materials using concentrated sunlight, in particular, superconducting ceramic materials. He also achieved significant results in this area. In particular, he calculated the distribution of the temperature field in the sample for various materials when exposed to sunlight. The good agreement between theoretical calculations and the measurement results was shown.

The research activity of Baizakov after 1995 is connected with the theory of nonlinear waves in Bose - Einstein condensates and optical fibers. The main scientific results in this area are as follows:
A theory of soliton propagation in optical fibers with varying dispersions and nonlinear coefficients was developed. The limits of soliton stability were found, when the parameters of the optical fiber are periodic and random. It is shown that these results can be used in optical fibers information transmission systems (1995-2000).
The existence of discrete solitons of matter waves arising in a Bose - Einstein condensate under the action of an optical lattice potential was shown. Using the strong coupling method, a discrete version of the nonlinear Schrödinger equation was obtained (2001).
For the first time the existence of stable solitons of matter waves in a Bose condensate placed in two- and three-dimensional optical lattices was shown. The process of modulation instability in the Bose-Einstein condensate was shown as the cause of the appearance of solitons (2002-2003).
Using the Ginzburg-Landau equation, it was shown that dissipative solitons can continuously move in a given direction and remain stable (2004–2007).
It was shown that the phenomenon of scattering of solitons of matter waves in a Bose-Einstein condensate is fundamentally different from the scattering of wave packets in quantum mechanics due to the nonlinear nature of the condensate (2008-2011).
B. B. Baizakov is a highly qualified specialist in the physics of optical solitons and Bose-Einstein condensates. He has conducted research at the University of Salerno in Italy in the period 2001-2005 and 2006-2007. He has given a talk at National and International scientific conferences many times. He has more than 70 articles published in leading international journals, and including (in brackets the number of articles) Phys. Rev. A, E (14), Journal of Physics B (3), Physica D (2), Europhys. Lett. (1), Phys. Lett. A (1), Optics Letters (1), Int. J. Mod. Phys. (1) Modern Phys. Lett. B (1), European Physics Journal D (1), Theoretical and Mathematical Physics (1), Physica Status Solidi (1), Journal de Physique (1), Applied Solar Energy (3).

B. B. Baizakov was a member of the organizing committee of several international conferences (1. International Seminar: Nonlinear waves; July, 2011, Tashkent, Uzbekistan; 2. International Conference: Nonlinear Waves: Theory and Experiment, 15 -18 January 2008, Tashkent, Uzbekistan; 3. Mini-Workshop: Bose-Einstein Condensation, University of Salerno, 19-20 December 2001, Baronissi, Italy; 4. Advanced Research Workshop: Nonlinearity and Disorder: Theory and Applications, 2- 6 October 2000, Tashkent Uzbekistan). He is a reviewer of international journals (Phys. Rev. Lett., Phys. Rev. A, E, Phys. Lett. A, Opt. Communications).

B. B. Baizakov actively participates  in the training of young scientific researchers. He supervises  master’s  theses and diploma works of undergraduate students at the Physics department of the National University of Uzbekistan.
