Research

My broad, interdisciplinary research interests are in the fields of marine ecosystems and climate variability, fisheries oceanography, climate change impacts on living marine resources, sea turtle biology, ecosystem modeling, and ocean color derived phytoplankton variability. I'm particularly interested in the trophic cascading dynamics within marine ecosystems between lower trophic primary producers and higher trophic organisms through both large- and small-scale climate variability. This includes both bottom-up factors such as resource availability and top-down factors including climate change and fisheries. Since joining the NMFS Northeast Fisheries Science Center's Ecosystem Assessment Program, my current research has mainly focused on the U.S. Northeast Continental Shelf Large Marine Ecosystem. I'm investigating the implications of climate forced changes in phytoplankton abundance and size-class structure on upper trophic fishery resources and protected species. Additionally, I'm considering climate-forced changes in the critical habitats of various species in terms of physiological constraints (i.e. temperature and oxygen) and larval settlement (circulation changes). Understanding contemporary relationships between climate, oceanography, and lower/upper trophic levels is a critical step towards assessing potential impacts of climate change on living marine resources. My research is geared to aid in the process of moving forward towards Ecosystem-Based Fisheries Management. The complex biophysical interactions within marine food webs, coupled with the complicated business of assessing the impacts of fisheries on marine ecosystems (and vice versa) requires interdisciplinary research to elucidate the primary mechanistic underpinnings driving historical, contemporary, and future variability/trends of living marine resources. To accomplish this, I collaborate with a wide range of fellow scientists at NMFS and GFDL, along with those in academia and other national/international organizations.
