RESEARCH INTEREST: My research focuses on the populational divergence in butterflies in the genus Heliconius and their geographical races, using these as a model  to understand evolution of the animal genitalia. At the moment work in aspects like the rapid morphological diversification  of the male genitalia of these butterflies with the purpose of find evidences that support the evolution hypothesis for sexual selection and criptic preference of the female. 
Other topics of interest are: preferences of mating in insects, sexual selection,  speciation, applications of geometric morphometrics and multivariate morphometrics in evolutionary biology. Others:  Onychophora for Colombia.
