Research Background
Connecting theoretical and empirical applications to tackle applied ecological questions has been an underlying theme throughout my research.

Prior to joining WHOI, I was a postdoctoral researcher with Dr. Alan Hastings and Dr. Jim Sanchirico in the Department of Environmental Science and Policy at UC Davis. As a postdoctoral fellow with the Bahamas Biocomplexity Project, my work focused on how marine reserves might alter community dynamics, susceptibility to bioinvasions, and the bioeconomic tradeoffs associated with ecosystem-based fisheries management.

I received my Ph.D. in Ecology, Evolution and Marine Biology from UCSB in June 2004 under the guidance of Dr. Steve Gaines and Dr. Roger Nisbet. My dissertation work examined the implications of spillover, density-dependence, and fishing behavior for marine reserve designation using spatially-explicit models. As a graduate and undergraduate student, I also participated in a number of projects focused on watershed restoration, intertidal runoff, aquaculture development and diesel contamination in a salt marsh.

Knauss Marine Policy Fellow
While a Knauss Marine Policy Fellow with the NOAA Biogeography Branch, I primarily contributed to two projects: (1) A biogeographic assessment of the Channel Islands National Marine Sanctuary, and (2) A report on the state of coral reef ecosystems of the U.S. and Freely Associated States. Integrating scientific research with coastal resource management is central to my research and I continue to build upon my former fellowship experience through working groups and collaborative projects that bring together ecological and socioeconomic studies.
