I have expertise in Arctic fjords systems science, being educated in the field of oceanography, paleoceanography and sedimentology. My recent interests are the sea-environmental changes in European Arctic after last glaciation and modern processes resulting from the recent climate changes. Among them, the most interesting for me are sedimentation, interaction between fresh and salt water and supply of the terrigenous matter to the fjords and Arctic shelf with applications to the post-glacial climate changes study. Since science is the team effort, and I work with marine biologists, I also study the biological implications of the solids flux and sediment dynamics in the Arctic seas.
During 30 years of my professional activities I spent more than 50 months in European, American and Russian Arctic regions working in different scientific programs.

Ongoing projects:
  • Sedimentary ancient DNA - a new proxy to investigate the impact of environmental change on past and present biodiversity in Nordic Seas.
  • Multiproxy analysis of the sea surface temperature impact on primary productivity of the western and northern Svalbard shelf in the Holocene
  • Holocene history of the Greenland Gyre
  • Dinocysts as the paleoceanographic indicator of the sea ice. Late Holocene history of the sea environment of Hornsund and Storfjorden (Svalbard).
  • Paleogentic reconstruction of Atlantic water advection into the Arctic Ocean over the Holocene.
  • Paleogenetics record in marine sediment as a new tool for reconstucting of the sea environmental changes in the Arctic.
  • Foraminiferal studies in European Arctic fiords
  • Atlantic water advection to the European Arctic in Holocene. Paleoceanographic record of the West Spitsbergen Current fluctuation.
  • Modern climate changes and their influence on fjords environment.
