Research Interests
My aim is to develop efficient molecular biodiversity assessment pipelines that leverage genomic, spatial, and ecological information to capture global change phenomena of the world’s biotas.
I received my PhD from the Department of Environmental Science, Policy and Management at University of California, Berkeley after working with Dr. Rosemary Gillespie. I have a MS Biology from Sonoma State University where I worked with Dr. Derek Girman and Dr. Brian Fisher investigating a group of ants from Madagascar that have specialized across the island due to divergent colony reproductive strategies and variable microhabitats.
I am broadly interested in species diversification mechanisms of insular fauna and how communities change over time; in particular, how anthropogenic changes are altering species interactions and potentially driving rapid evolution. To investigate these questions I study arthropod communities in the Hawaiian archipelago that include endemic and native species as well as accidental and purposeful introductions. I exploit the natural occurrence of age-structured terrains on the archipelago that represent communities in an assembly continuum at sites dating from 44 years to 5.5 million years in geological age.
