I am conducting research on the food webs and microorganism community structures in aquatic ecosystems such as lakes, wetlands, rivers, and estuaries using stable isotopic analysis and molecular phylogenetic analysis.

We are researching food web structures using stable isotopic analysis in wetland ecosystems such as the Lake Chany complex (Western Siberia, Russia) which includes inland saline as well as fresh water lakes, and Lake Izunuma (Miyagi Prefecture) which is a shallow lake with wide vegetation comprised of aquatic macrophytes. We have also started to incorporate host-parasite relationships into the food web structure analysis of these wetland ecosystems. In addition, we aim to study bacterial communities, and their biotic structure and environments in wetland ecosystems using DNA based phylogenetic analysis and fluorescent in situ hybridization methods.


Although I am currently conducting research mainly on lake ecosystems, I’d like to expand the scope of my student themes to various aquatic environments.
