Assistant Professor of Civil and Environmental Engineering
Dr. Andrew D. Bragg’s research focuses on fundamental and applied problems in fluid dynamics, especially turbulence.
Particular problems include understanding the microphysical processes governing rain formation in clouds and their implications for global climate, the mixing of organisms in the ocean, water treatment, and the dispersion of pollution in the atmosphere, along with astrophysical and industrial problems. His approach to solving these problems combines methods from applied mathematics and statistical physics, along with high-performance computation. Recent interests also include ecohydrology, porous media flows and geophysical fluid dynamics.
Before joining the Duke University faculty, Dr. Bragg was a postdoctoral associate in the Applied Mathematics and Plasma Physics Group at the Los Alamos National Laboratory. Prior to that, he was a postdoctoral associate in the Sibley School of Mechanical and Aerospace Engineering at Cornell University. Dr. Bragg obtained his PhD in Theoretical Fluid Dynamics from Newcastle University in England.
