Research Interests

My research involves the physics of the nearshore coastal ocean including waves, currents, and sediment transport. I'm interested in using new observational and modeling tools to understand and make predictions of these processes --- often using a probabilistic approach owing to the dynamic/complex nature of the problem.

Examples:

- measuring statistics of fluid-sediment interaction at the seabed, using new instrumentation (e.g. acoustics)

- instrumenting beaches to measure shoaling and breaking waves, and their interaction with seabed roughness

- using beach cameras (Argus) with model-data assimilation to improve forecasts of nearshore currents (e.g. rip currents)

I've also been involved in applying the same techniques in similar environments such as rivers and inlets.

NOTE: Interested in joining my research group as a grad student, or gaining undergraduate research experience?  I'd love to hear from you!  Please contact me (wilsongr@coas.oregonstate.edu) with a brief description of your background and interests.
