Hold progressively responsible positions: Group Leader (74-79), Head of the Laboratory (1979-87), Department Chair (1987-91), all at Russian Academy of Science.

By using enzyme-kinetic and inhibitory analyses, pioneered in revealing TCDD-induced CYP1B1 (FEBS Letters, 1987). Invented the recombinant and TCDD-induced microsomal and isolated monooxygenase isoforms CYP1A1 and CYP1A2, to study regulatory effects of bioflavonoids on procarcinogens metabolism in humans (BBA, 1994). Since the discovery of trans-activation effect of TCDD on HIV-1 (BBRC, 1991), have established Xenobiotical Virology, a biomedical discipline dealing with mechanisms of dioxin effects on DRE-containing genes of human viruses, transcription factors and cytokines linked to inflammation and malignancy pathways.
