I am a plant systematist interested in describing, documenting, and studying flowering plant diversity and evolution. I use the evolutionary relationships among species as the basis for studying how they have diversified, as well as to provide a temporal and spatial framework for understanding evolutionary transitions. I draw upon a variety of data sources that include herbarium specimens, DNA sequences, morphology, micromorphology, anatomy, the fossil record, carbon isotope ratios, and ecological niche modeling.

 

Since January 2010 I am a postdoctoral fellow at the Department of Botany working for the PBI: Miconieae project under the supervision of Dr. Frank Almeda. Currently, I am participating in the following projects: a) Characterization, systematic value, and evolutionary patterns of seed micromorphology in the Miconieae; b) Divergence times estimation for the major lineages of Miconieae; c) Taxonomy, molecular phylogenetics and systematics, biogeography, and character evolution in the species of the Secundiflorae clade (Leandra sect. Secundiflorae and Ossaea sect. Diclemia); d) Preparation of morphological descriptions of selected Miconieae species from Mexico, Central America, and Colombia, and e) Plant collecting of Colombian species of Miconieae.
