Fields and Interests

Ecosystems Ecology with stable isotope techniques:
Biogeochemical cycles of materials (N, P, C, S, O, H, Si, Fe)

Isotope/Isotopomer technique for biogeochemical cycle studies

Anoxic environment (CH4, N2O dynamics in soil and water)

Ecosystems Ecology (plant - soil systems featuring microbial function)

Marriage of Environmental Economy and Ecosystems Ecology for more appropriate evaluations of ecosystems

Systems themselves (as nitrogen cycles, ecosystems, human systems, www etc.)
