Research interests

I’mcurrently working on establishing a data assimilation system to link various data sets with different spatial and temporal resolutions into a format that allows for quality control and exploitation of forest-related data at a Swiss scale. I received a doctorate degree on September 2017 in field of Forest Ecology at Czech University of Life Sciences, Prague. My work mainly focused on disentangling effect of different exogenous and indigenous factors on tree and stand level growth and biomass accumulation, stand dynamics and disturbance history, and forest biodiversity. I’m passionate about using working tools as R, Fortran, SQL, ArcGis to uncover meaningful information from large and variable data-set into tangible scientific publications. My activities are associated to leading universities (ETHCULSHarvard ForestWSLSLU) and in widely distributed forest research sites (Europe: Ukraine, Romania, Slovakia, Czech Republic, Bosnia; Asia: Russia; and North America: New England).

WSL Projects

Modelling forest growth using 3-PG

Testing 3-PG in uneven-aged forests, comparing predictions with an empirical model and developing a 3-PG R package.


Our aim is to estimate Swiss forest net ecosystem productivity (NEP) at monthly or seasonal resolution for each individual year in order to link biomass changes over time with global drivers.
