David has been a Research Fisheries Biologist at the Northeast Fisheries Science Center since 2009. His research addresses the ecology of marine fishes, with a specific focus on the early life stages. Research at the NEFSC has addressed mechanisms underlying multi-decadal patterns in the abundance of small pelagic species, and the effects of these patterns on predator species such as Atlantic cod. Prior to joining the NEFSC, David was a PhD student at the University of Miami Rosenstiel School of Marine and Atmospheric Science. The primary focus of his PhD research was on characterizing the physical and biological characteristics of billfish spawning areas at both fine scales, such as sub-mesoscale eddies, and at larger regional scales.
