I am interested in spatio-temporal patterns of plant evolution in the Andes cordillera of South America. Currently, I am working with the genus Diplostephium (Compositae), which comprises a rapid radiation with more than a hundred species distributed from Venezuela to northern Chile. My research focuses on the taxonomy, phylogeny, anatomy, and biogeography of the genus. I am trying to elucidate Diplostephium's rate of speciation, biogeography, time of colonization to the paramo, and key adaptations.
