Ecosystems: I work with physical oceanographers and fisheries scientists to better understand how Alaskan marine ecosystems respond to changes in the environment. Some environmental changes that have occurred include warm events such as the Blob in the Gulf of Alaska, stanzas of climate variability in the Bering Sea, and reductions in ice concentrations in the arctic.

Innovative Technology: I am a lead PI for the Innovative Technology for Arctic Exploration program which develops and deploys innovative platforms and sensors in the arctic. Some of these innovations include the Saildrone, the Oculus coastal glider, and the air-deployed ALAMO floats.

Global Hydrography: Though a partnerships with Scripps and NOAA/AOML, the GO-SHIP CLIVAR hydrographic program continues to build the premier deep-water global nutrient data set. These data were a valuable contribution to the latest Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report.
