Currently I am a PhD student within GHG Europe measuring and modeling CO2, CH4 and N2O fluxes between three grassland ecosystems and the atmosphere. My aim is to better understand the complex interactions between biotic/abiotic drivers and GHG fluxes. Also I want to provide a GHG balance for a three stages farming system.
Research interests
- Global change
- Terrestrial carbon cycling
- CO2, CH4 and N2O fluxes
- Eddy covariance and chamber measurements
- Modelling greenhouse gas fluxes between grassland ecosystems and the atmosphere
