Primary interests

My research focus is on the biological, hydrological, and geographic characteristics of wetlands as indicators of functions. I apply the results in providing advice to local, state, national and international governmental and non-governmental agencies that implement wetland management and regulatory programs.

Future Projects

  • Application of freshwater wetland assessment in the northwest region of the Russian Republic
