Research Interests:

I am interested in the phylogenetics and diversity of invertebrates, with current particular interest in arachnids. Advances in molecular and genomic data combined with morphological information make this an exciting time for exploration of understudied taxa. With estimates of as many undescribed species as those known to science, there is still much to know about these ubiquitous animals. My previous academic endeavors include the revision of the Nearctic fauna of the formicine ant genus Nylanderia, description of the Caribbean ant genus Zatania, and identification of the Raspberry crazy ant pest in the Gulf states, N. fulva.
