He graduated from the Baku State University and the Lomonosov Moscow State University in 1983 before being awarded Ph.D. degree in 1990 and D.Sc. (Habilitation) in 1997 from the Russian Academy of Sciences in Moscow, Russia. Ismail-Zadeh has been affiliated with the Azerbaijan National Academy of Sciences, Institute of Geology and Geophysics (1983-1986, 1990–1992). He has been chief scientist, research professor and scientific leader of research group "Computational Geodynamics and Geohazard Modeling" of the Russian Academy of Sciences Institute of Earthquake Prediction Theory and Mathematical Geophysics, Moscow (1992–2022).

He has been a visiting scholar, lecturer and professor at several universities and academic centers, including the University of Cambridge (UK), University of California at Los Angeles, the University of Tokyo (Japan), Institut de Physique du Globe de Paris (France), the University of Uppsala (Sweden), and the Abdus Salam International Centre for Theoretical Physics in Trieste (Italy).

Research
Ismail-Zadeh has conducted research in the fields of geodynamics, seismology, sedimentary geology and tectonics (incl. research for hydrocarbon industry), geohazards, risk analysis, science diplomacy and history. His research methods cover multi- and interdisciplinary synthesis, theoretical analysis, and numerical experiments. He is a principal author and co-author of over 120 peer-reviewed papers and several books published by the Cambridge University Press, Springer Nature, and others.
