Profile

My research focuses on the evolution and systematics of Neotropical plants and animal-plant interactions. I have focused most of my research in the large tropical family Melastomataceae. Currently I am working on an analysis of relationships within the tribe Miconieae, using molecular, anatomy and morphological data (in collaboration with Walter Judd & Darin Penneys, University of Florida, Renato Goldenberg, Universidade Federal do Parana). These phylogenies will be used for the study of character evolution within the group. I am particularly interested in ant-plant symbiotic relationships, especially in those cases in which the ants nest on the plant, protecting the plant against herbivores (myrmecophytism). This type of associations are present in over 80 species of Melastomataceae and have evolved independently in different lineages. I am also interested in the evolution of the grass family (Poaceae) and its close allies (Ecdeicoleaeceae, Restionaceae and Joinvilleaceae), a group of small rush like plants from Australia and South Africa (in collaboration with Jerry Davis, Cornell University and Dennis Stevenson, NYBG). I have also done research on plant ecology and floristics in the Guayana Highlands (tepuis) in southern Venezuela. Currently I am interested in studying processes that lead to the high level of insectivory among tepui plants (another type of animal-plant interaction), and the also high levels of plant endemism.
