As part of the MHUA specimen collection, we have been also storing amphibians and reptiles tissues for genetic research and so far we harbor one of the largest specimen-vouchered tissue collection in the country. Our research interests are to understand the patterns and processes that have led to the high diversification in the Neotropical fauna. By combining morphological and molecular data with statistical phylogenetics, historical demography methods and ecological niche modeling, we aim to uncover the complex processes of lineage diversification in the Colombian herpetofauna. We also maintain active collaboration with national and international researchers aiming to make inferences across larger spatial and taxonomic scales.
