My main interest is paleoecology. My research is articulated into two directions: the past and the present.
I use phytoliths - micriscopic silica bodies produced by plants and preserved in fossil soils and sediments - to recosntruct the structure and the evolution of vegetation through time and space.
I also use phytoliths from modern soils, in order to better understand how well they represent the standing vegetation in different habitats, and to define the guidelines for fossil studies that use phytoliths to infer spatial variation in habitat structure.
My main study areas are southern Patagonia (plaeoecological study), Costa Rica, and Colombia (modern study).
