Biography

I am a physical oceanographer at the Scripps Institution of Oceanography. My research interests include oceanic processes like dense overflows and hydraulics, internal waves and turbulent mixing, and their impacts on the large-scale ocean circulation. My research is primarily based on the collection and analysis of shipboard and moored in-situ observations. I am a member of Multiscale Ocean Dynamics at Scripps.
