My current research interests focus on how variation in the arrival or timing of species invasions influences species interactions and the establishment of species in communities.

Through my research on Santa Cruz Island, I seek to contribute to the understanding of the variable impact of different plant invaders on arthropods and the mechanism of this impact.

I study the effects of Arundo donax on braided channel planform (active channel width, braiding index, and island size) in the Santa Clara River in Ventura County, California. Part of this study will include soil coring to determine the the density and diameter of roots and rhizomes at different depths in the banks and floodplains.

I study the relationship between Tamarix taxonomy and Diorhabda herbivory, and is working in the Virgin River to track seasonal impacts to Tamarix species and haplotypes in the river
