I am a professor in Facultad de Estudios Superiores Zaragoza, UNAM. I am a collaborator at Coleoptera collection in the same institution. I am a member of the network of researchers of Lab. Zaragoza. My research interest is the systematics and taxonomy of leaf beetles (Chrysomelidae), especially members of the subfamily Cassidinae. My research integrates phylogenetics, natural history, ecology, historical and ecological biogeography of leaf beetles.
