Professor Oks received his Ph.D. in 1975 from Moscow Institute of Physics and Technology and his Doctor of Sciences in 1985 from the Institute of General Physics, Academy of Sciences, Moscow. The latter degree "is awarded only to outstanding Ph.D. scientists who founded a new research field of great interest." Prior to coming to the Auburn University, Professor Oks held a variety of senior research positions in the Soviet Union and later in Germany.

Professor Oks authored or co‑authored about 300 publications in various research fields, such as FRONTIERS OF QUANTUM MECHANICS, PLASMA SPECTROSCOPY, LASER PHYSICS, and NONLINEAR DYNAMICS OF RYDBERG ATOMS. He also gave numerous invited lectures at international conferences.

He authored 3 monographs, the two latest ones being titled: “Stark Broadening of Hydrogen and Hydrogenlike Spectral Lines in Plasmas: The Physical Insight” (Alpha Science International: Oxford, United Kingdom) 2006 and "Plasma Spectroscopy: The Influence of Microwave and Laser Fields" (Springer: Berlin) 1995.

He founded/co-founded and developed new research fields:

  • INTRA-STARK SPECTROSCOPY (new class of nonlinear optical phenomena in plasmas that has an analogy with intra-Doppler spectroscopy in nonlinear optics;
  • MASING WITHOUT INVERSION (advanced schemes for generating/amplifying coherent microwave radiation);
  • QUANTUM CHAOS (nonlinear dynamics in the microscopic world).

He is a member of the Program Committees of two International Conferences: the bi‑annual conference "Spectral Line Shapes" and the annual Zvenigorod Conference on Plasma Physics and Controlled Fusion. For 9 years he was the Associate Editor of the Journal of Quantitative Spectroscopy and Radiative Transfer. His achievements have been also recognized by the Dean's Research Award (1996) and by the Alexander von Humboldt Foundation (1988).
