Research interests

My research interests revolves around tropical dendrochronology. Dendrochronology, or the study of tree rings, is a powerful tool to reconstruct past climate change, but is also extremely valuable when studying forest productivity, carbon sequestration and vegetation dynamics. In addition to classical dendrochronological techniques (ring width measurements) I also use the wood anatomy, stable isotopic composition and chemical composition of the wood to extract environmental information recorded in the trees.
