My research spans forest ecophysiology and functional ecology, with the aim of improving our understanding of tree functioning and biogeochemical cycling in forest ecosystems, especially in the way they respond to climate change.

 

To this aim, I use a variety of data sources (including leaf-level physiological measurements, Eddy-covariance towers, forest inventories and satellite-derived imagery) in combination with statistical and ecophysiological process-based models.

 

 

 

I am currently mainly involved in two research topics.  

Ecophysiology of tropical tree species used in restoration project. Dynamic of restored planted forests and influence of management. Mechanisms underlying tree resistance to drought. Biological mechanisms underlying biodiversity‐ecosystem functioning relationship in forest ecosystems. Scientific bases for tropical forest restoration and silviculture guidelines. 

Sustainable management of fast-growing tropical tree plantations

Long-term monitoring of carbon, water and energy cycling in Eucalypt fast-growing plantations. Provide scientific bases to reduce the environmental impacts and sustain productivity of plantations in the context of climate change.
