BIOGRAPHICAL NOTE
My main interests are the systematics, behavior, and evolutionary biology of insects, especially ants (Formicidae) and parasitic wasps (Scoliidae). In particular, I am very interested (as part of my graduate studies) in conducting the systematic revision of the primitive non-leaf-cutting fungus-growing ant genus Myrmicocrypta, and the construction of coevolutionary hypotheses including the ants and their symbionts (fungal cultivars, Escovopsis weed molds, and Pseudonocardia, antibiotic producing bacterial mutualism). To do so, I am planning to use both morphological and molecular approaches as well as data obtained from behavior and natural history to conduct this revision. Taxon sampling will include representative species from the genera that currently comprises the Attini (Formicidae: Mymicinae), and representatives from other Myrmicinae tribes, especially the tribe Blepharidattini (genera Blepharidatta and Wasmannia) which have been proposed to be the sister group of the attines. To determine the relationships of the species within the genus, I will employ both morphological and molecular characters including, for the former, characters of all castes and life stages and, for the latter, the nuclear genes wingless, 28S, EF1-alpha F1 and F2 paralogs, and LwRH opsin, and the COI mitochondrial gene. Mitochondrial COI gene has proven to be at an appropriate rate of divergence for examination of species level relationships. I am also currently conducting the world revision of the spider-egg predator ant genus Discothyrea (Proceratiinae) with Dr. John LaPolla (Towson University), using both morphological and molecular approaches. I am also conducting biodiversity studies in Central and South America in collaboration with Dr. Ted Schultz (NMNH-SI) and Dr. John LaPolla (Towson University), and comparing the ant fauna in the Guyana Shield vs. the Amazonian forest to extrapolate patterns of endemism and to identify areas of conservation concern.
