<p>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&nbsp;<strong>complicated</strong> fluid dynamics: problems involving turbulence, phase changes, magnetic fields, traditional "complex" non-Newtonian fluids, or various combinations of them.&nbsp;<br>In order to tackle this menagerie of problems, we contribute to and use the <a href="http://dedalus-project.org">Dedalus Project</a>, a flexible framework for solving partial differential equations.&nbsp;<br>Prof. Oishi is one of the founders and core developers of Dedalus, and the other developers regularly visit and collaborate with our group.</p>
