She led 25 archaeological expeditions and participated in over a hundred, mostly in the Eurasian steppe region.

She was also an academician, member of the Russian Academy of Natural Sciences (1988), Corresponding Fellow of the German Archaeological Institute (1982), member of the Italian Società Iranologica Europea (1996), and of the European Association of South Asian Archaeologists.

[4] Kuzmina published more than 300 articles and 15 books on the archaeology of the Eurasian Steppes, the origins and migrations of Indo-Iranians, their mythology and arts, and essays in museum policies.

The thesis presented in the book is that a number of genetically related tribes consolidated around the steppes representing the Andronovo horizon and that, for various reasons, the tribes speaking Iranian languages emerged as the dominant ones among them.

Kuzmina presents her case based on extensive archaeological evidence.
