Fields of interest: 
Dendroclimatology, Paleoclimatology and Ecology in Mediterranean, Boreal and Tropical ecosystems.



My research interest is to understand the interactions between forests and climate applying dendrochronological techniques, using these relationships: (1) to study ecological processes such as forest response to climate; (2) to estimate climatic conditions before the existence of instrumental records (paleoclimatology).
