My research focuses mainly on understanding the evolutionary processes and mechanisms that generate phenotypic and species diversity, mostly in poison frogs of the family Dendrobatidae. For my PhD, I am working to identify the evolutionary genetic and developmental processes through which multiple lineages of Phyllobates poison frogs have convergently evolved bright-yellow coloration, dangerously high toxicity, and larger sizes. I approach this question from multiple angles, including phylogenetics and phylogeography, develompent and gene expression, and genetic mapping and association studies. I also maintain an active research line on the systematics and taxonomy of Dendrobatid frogs, especially the genera Andinobates, Phyllobates, and Silverstoneia, in collaboration with researchers at Universidad de los Andes in Colombia. Apart from my work on poison frogs I have collaborated on projects aiming to describe or understand the processes that generate biodiversity, such as elucidating the relationship between bird migration and speciation in Tyrant Flycatchers, or delimiting the species of pathogenic fungi of the genus Histoplasma.
