I am currently posted at the Hufbauer lab in Colorado State University, Fort Collins, CO. Our lab focuses on applied evolutionary ecology (http://www.hufbauerlab.org) and my projects have focused on biological invasions and the evolutionary ecology of an invasive species.
PhD in Ecology
For my PhD I will return to my island of Guam and try to disentangle the food-web connections. I am hoping to understand shifts in arthropod abundance, behavior and roles due to the invasion of the brown tree snake (Boiga irregularis) and loss of native birds. I will look at how insect abundance differ in areas with birds and without birds, the type of predation that is occuring, the roles of new predators in the community, and evaluating possible changes in anti-predator behavior in butterflies.
