I then did a postdoc at Scripps Institution of Oceanography studying estuarine-nearshore connectivity of the Tijuana River Estuary.  I love the interdisciplinary nature of oceanography and am intrigued by the feedbacks that link physical, chemical, and biological processes.  My ongoing research interests focus on the interconnected dynamics driving transport within and exchange between coastal subregions, such as the inner-shelf, surfzone, and estuaries.

I am currently studying the shoreward-propagation of non-linear internal waves (NLIWs) on the inner-shelf of central California.  Specifically, I’m investigating how stratification variability on the shelf both affects and is affected by NLIWs. My project is one component of a large, ONR-funded Inner-Shelf project which involved an extensive field campaign.  More information on the broader project can be found here:  Inner-Shelf Experiment Blog

My dissertation focused on the 3-dimensional circulation and sediment transport processes in the Delaware Estuary.  Specifically, I studied how sediment transport mechanisms vary spatiotemporally and impact an estuary’s ability to trap sediments from riverine and shelf sources.  I also investigated how sediment dynamics can impact productivity  in light-limited systems, thus  influencing  estuarine biogeochemistry and ecosystem function.
