Broadly, my interests are in physical oceanography and biogeochemistry. I use statistical methods paired with models, observations, and theory to gain dynamical information about the upper and coastal ocean.

Convergence Zones & Surface Drifter Statistics

  • Drifters are often entrained into fronts or remain in long-lived eddies for extended periods of time.
  • These drifter trapping features prevent the floats from adequately sampling the entire domain.
  • I am interested in quantifying statistical biases due to this sampling pattern.
  • See a series of webinar presentations about GoMRI efforts in the Gulf of Mexico here.

Structure Function & Spectral Theory

  • Upper ocean statistics are powerful metrics useful for classifying turbulent regimes.
  • I develop structure function and spectral theories for anisotropic turbulence as well as reactive tracers.

Eulerian & Lagrangian Data Assimilation

I incorporate both Eulerian and Lagrangian traffic flow observations using data assimilation schemes to improve macroscopic traffic models and estimate difficult parameters to observe.
