My research addresses a broad range of questions that span local to global scales, including spatial population dynamics, trophic interactions in community ecology, conservation planning, and the interface between ecology and human dynamics, all with the ultimate aim to inform and facilitate conservation and resource management efforts in marine (and other) systems. I have led and participated in several key synthetic research projects that have advanced our understanding of the state of the world’s oceans and the potential for marine reserves to improve ocean condition. In particular I led the development and mapping of cumulative impact assessments at global and regional scales in marine and freshwater systems, and continue to serve as the lead scientist for the Ocean Health Index project. Field expeditions have included spots in tropical and temperate systems in the Caribbean, Red Sea, Mediterranean, Solomon Islands, Indonesia, various parts of the South Pacific, California and Chile.

I received my Bachelor’s of Arts in Biology from Carleton College (USA) in 1995, an my Ph.D. in marine ecology in 2003 from UC Santa Barbara, California (USA). I then held a joint post-doctoral fellowship at the National Center for Ecological Analysis and Synthesis (NCEAS) and the Smith Fellowship Program sponsored by The Nature Conservancy.  I was a Research Associate at NCEAS until 2013 and then appointed Professor in the Bren School of Environmental Science and Management at UC Santa Barbara. I also serve as the Director of the Center for Marine Assessment and Planning (CMAP) at UC Santa Barbara.
