Research Interests

I am broadly interested in both the theoretical and applied aspects of invasion ecology. Specifically, I am interested in the ecological consequences of biological invasions.

For my dissertation research I am elucidating the mechanisms by which mosquito populations dynamics is influenced by environmental heterogeneity created by invasive aquatic macrophytes in the California Delta, one of several areas in the state where West Nile Virus incidences have been on the rise in the past several years. The mosquito species I am studying is Culex pipiens, a primary vector of West Nile Virus. Included in my studies are three invasive aquatic macrophyte species -- Water hyacinth,Eichhornia crassipes (S. America), Water primrose, Ludwigia hexapetala (C. and S. America), and Brazilian waterweed, Egeria densa (S. America). Each of these plant species are of a specific form: floating, emergent, or submergent, a characteristic that may influence the type of microhabitat provided to mosquito populations.
