Prof. Abdullaev was born on 14 January 1948 in Tashkent city, Uzbekistan. In 1969 he graduated from the physics faculty of Tashkent State University (TSU). After graduation, he served in the armed forces from 1969 to 1971.

In 1971 he started post-graduate studies at the Institute of Nuclear Physics (INP) of the Academy of Sciences of the Republic of Uzbekistan (AS RUz) and then he was assigned to the Joint Institute on Nuclear Research (JINR, Dubna, Russia). He studied the theory of weak interactions and developed Lie models with non-polynomial Lagrangians and non-local interactions. He investigated the quasi-classical limit of quantum electrodynamics with gravitation. Results from these works are summarized in his PhD thesis “Theory of the weak interactions with non-polynomial Lagrangians” defended at the joint scientific council of the Academy of Sciences of the Republic of Uzbekistan.

After the stay at the Joint Institute on Nuclear Research, F. Kh. Abdullaev worked as a scientific researcher at the INP of the Academy of Sciences of the Republic of Uzbekistan and as an assistant lecturer in the Theoretical Physics department of the Tashkent State University.   

In 1977 he joined the staff of the Thermophysics Department (TPD) of the Academy of Sciences of the Republic of Uzbekistan. In 1983 he became the head of the Laboratory of wave processes at the TPD of the AS RUz.

In 1985 he defended the thesis “Dynamics of solitons in inhomogeneous media” for the degree of doctor of science at the Scientific Council of the Institute of Theoretical Physics (Kiev, Ukraine). In this thesis, the results of the theory of solitons in condensed media were summarized.

From 1986 to 1992 he worked as deputy director for science, and then as director of the TPD of the AS RUz. During that period, he published three monographs, two of which were translated into English.

From 1992 to 1997 he served as head of the expert council for physics of the High Attestation Commission of the Republic of Uzbekistan.

From 1993 till 2009 he worked as head of the Laboratory of the theory of solid state and semiconductors (now the Laboratory of theoretical physics) of the Physical-Technical Institute of the Uzbek Academy of Sciences.

Since 1987 Prof. F. Kh. Abdullaev has been a guest in scientific institutions in Australia, United Kingdom, Germany, Brazil, Greece, Denmark, Italy, Spain, Malaysia, Portugal, USA, France, and Japan.

F. Kh. Abdullaev was the organizer of several international scientific conferences in Tashkent. He started the organization of international conferences on nonlinear and chaotic phenomena in 1990 (“Nonlinearity and Disorder”) and NATO ARW`s (Co-Director) in 2000 (“Nonlinearity with Disorder: Theory and Applications”) in Tashkent and in 2004 “Nonlinear Waves Classical and Quantum Aspects” in Lisbon. He was an invited speaker in 25 scientific meetings, held in the USA, Germany, France, Spain, Portugal, Italy and Brazil.  

F. Kh. Abdullaev has been awarded various national and international grants (including CRDF, INTAS, ISF, NATO, and JSPS) for research on fundamental problems of nonlinear physics.  

Publications include more than 200 articles in refereed journals and 4 books.
