The author of over 1500 scientific publications. His research interests include the study of prehistoric art monuments, their chronology and semantics; the investigation of burial and settlement complexes from the Neolithic to the Late Middle Ages; staurography; and issues in the history of science and science studies. Under the direction of V.I. Molodin and with his direct participation, a number of first-class archaeological sites were discovered and studied, yielding new data on the ancient history of the indigenous peoples of Siberia. He is the author of the first detailed scientific concept of the ethnogenesis and cultural genesis of human populations inhabiting the West Siberian Plain within the chronological boundaries from the Upper Paleolithic to the Late Middle Ages. He has significantly supplemented and refined the cultural periodization of the Early to Developed Bronze Age in the Baraba forest-steppe, which has received reliable stratigraphic confirmation. He developed the concept of migration impulses by carriers of the Andronovo cultural-historical community into the Baraba forest-steppe.

One of the initiators of the study of the high-altitude regions of Altai, during which unique burial complexes of the Pazyryk culture were discovered and studied, enriching the global fund of fundamental historical knowledge. He discovered and studied: the complex of Pazyryk culture burial grounds on the Ukok Plateau; the proto-urban settlement of Chicha in the Zdvinsky District of the Novosibirsk Region; and a Pazyryk warrior burial in the northwestern part of the Mongolian Altai, unparalleled in its state of preservation. He conducted a monographic study of the Sopka-2 burial and ritual complex, whose burials and ritual structures belonged to periods from the Neolithic to the Late Middle Ages (materials published in 6 volumes). He discovered and studied an early (Upper Paleolithic) layer of rock art in the south of the Altai Mountains and Mongolia, named the Kalgutinsky style petroglyphs. He developed a classification of Christian plastic art from the Ilimsk Ostrog and addressed a number of problems in Siberian staurography. He has supervised more than 60 candidates and doctors of sciences from Russia, Kazakhstan, the Republic of Korea, and China.
