Ben Halpern focuses his research at the interface of marine ecology and conservation planning. His research has addressed a broad range of questions that span local to global scales, including spatial population dynamics, trophic interactions in community ecology, and the interface between ecology and human dynamics, all with the ultimate aim of informing and facilitating conservation and resource management efforts in marine systems. After receiving his PhD in 2003, he 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. He was a research associate at NCEAS until 2013 and then appointed professor at the Bren School and part-time chair in marine conservation at Imperial College in London. He also serves as director of the Center for Marine Assessment and Planning (CMAP) at UCSB, and has been the lead scientist for the Ocean Health Index project.
