Systematics, Evolution and Taxonomy of Leptolycini (Coleoptera, Lycidae)
The Leptolycini is a group of paedomorphic beetles endemic to the West Indies. Members of this group are characterized by possessing adult females that lack the characters that define the adult form of a beetle: compound eyes, wings, elytra, 11 antennomeres, ovipositor and a multi-segmented tarsus. These extreme paedomorphic adult females are often termed “larviform” females, and in most cases, the status of a given individual as an adult or larvae is not really known.
In contrast, males of these sexually dimorphic species have all the normal adult characters and are immediately identifiable as a beetle. My current research is focused in unraveling the high diversity in this sexually dimorphic case of extreme paedomorphic beetles. A taxonomic revision, association of males/females and a species level phylogeny of the group is currently in progress.

Revision and Phylogeny of Thonalmus Bourgeois (Lycidae)
The genus Thonalmus is one of the most conspicuous and recognizable lycid beetles in the world, and probably the most studied genus among the Neotropical groups. The sole genus in its tribe, Thonalmini, and with a unique morphology and bright colors, the taxonomy and systematics at species-level is chaotic, and to the moment it identification of most species within the genus is impossible.
A taxonomic revision, molecular species-level phylogeny, as well as the diversification rates for the group is currently in production.
In addition to my PhD research I have the following research projects:

2) Revision of the World Omethidae (Coleoptera, Elateroidea)
3) Revision of the family Cneoglossidae Guérin-Méneville, 1843 (Coleoptera, Byrrhoidea)
I am also interested in the taxonomy of other families of Elateroidea and Byrrhoidea, including Cerophytidae, Phengodidae and Lampyridae and other odd balls within these superfamilies. See a full list of publications here.
