Douglas H. Kelley, PhD, is an Assistant Professor of Mechanical Engineering at the University of Rochester. Dr. Kelley earned a PhD in physics from University of Maryland (2009) and did postdoctoral research at Yale University and Massachusetts Institute of Technology before coming to U of R in 2013. Dr. Kelley teaches graduate courses on continuum mechanics and incompressible flow, as well as an undergraduate dynamics course. He and research his group study turbulent fluid mixing with application to energy and environment. One project focuses on the role of mixing in performance of liquid metal batteries, an emerging technology that may soon provide large-scale energy storage on worldwide electrical grids. Another project considers oceanic mixing of marine phytoplankton blooms. Phytoplankton naturally provide more carbon sequestration than almost any other reservoir on the planet, so climate models depend on accurate growth predictions. The two topics are united by common physics: they are problems of advection, diffusion, and reaction, in which scalars are mixed by complicated flows while local phase change proceeds.
