My research focuses on the evolutionary origin of the South American rainforests by looking at plant macrofossils. I am interested to know when and how the tropical rainforests appeared in the Neotropics, what mechanisms have produced the high species diversity and the characteristic family composition. I want to reconstruct the paleoclimatic, paleoecological and paleobiogeographical conditions under which the ancient Neotropical rainforest flourished, particularly during the Late Cretaceous, Paleogene and Middle Miocene. I am also interested on the systematic and taxonomy of Neotropical fossil plants.
