I lead the UNH Complicated Fluids group. We are interested in the basic physics of a wide array of fluid problems, including biophysical and geophysical flows. As the name implies, we solve complicated fluid dynamics: problems involving turbulence, phase changes, magnetic fields, traditional "complex" non-Newtonian fluids, or various combinations of them. 
In order to tackle this menagerie of problems, we contribute to and use the Dedalus Project, a flexible framework for solving partial differential equations. 
Prof. Oishi is one of the founders and core developers of Dedalus, and the other developers regularly visit and collaborate with our group.
