Research Statement
I am a community ecologist and
conservation biologist, and my
research is motivated by a
desire to understand and
effectively address
environmental problems. I study
the impact of biodiversity loss
on ecosystem services, with a
focus on seed dispersal and food
web dynamics in tropical forest
ecosystems. Much of my
research has taken place in the
Mariana Islands with the Ecology
of Bird Loss project. The Brown
Tree Snake (Boiga irregularis)
was introduced to the island of Guam in the 1940's and has has since caused the functional
extirpation of all native forest bird species on the island, resulting in the only contemporary
case of whole-island forest bird loss in the world. This has provided an opportunity to examine
the role of birds in pollination, seed dispersal, and food web dynamics.
