McKiver William

The focus of my research is in the area of geophysical fluid dynamics. I have studied many topics in this field ranging from theoretical aspects to more applied topics. In particular I have looked at how certain processes (turbulence and vortices, non-hydrostatic, modeling methods and resolved scales) affect ocean dynamics and marine biogeochemistry (plankton). I have worked to develop both mathematical models and numerical tools for obtaining a greater understanding of geophysical fluid dynamics, particularly the role of vortices, towards understanding how their interactions give rise to turbulence in large-scale geophysical flows.
