About

I use numerical models as well as remote sensing tools and field techniques to study ecohydrological and biogeochemical processes and dynamics in complex natural environments and agricultural systems. My main interest is to study how such systems react to human interference and climate change for a better understanding of the mechanisms behind land-atmosphere processes.
