Dmitriy Zharkov is the head of the Novosibirsk State University laboratory of protein engineering. He is a leading specialist in the field of fundamental mechanisms of DNA damage, DNA reparation and cell response to genotoxic stress. He has discovered several ferments of human reparation, defined special structures of some DNA-glycosylases and developed the theory of substrate specificity of ferments that recognize nucleic acids as dynamic multi-stage process.
