Reserach interests:
 

  • Biogeochemical transformations and transport of nitrogen and carbon in terrestrial and aquatic ecosystems
  • Stable isotopes of C, N, and O as tracers of biogeochemical processes
  • Greenhouse gas (CO2, CH4, N2O) emissions from surface waters and soils in peatland catchments under variable environmental conditions
  • Long-term effects of grazing on soil carbon sequestration
