Biography

Dr. Richter received his Ph.D. from Stanford University in 2011, having studied turbulence in non-Newtonian fluids. During a postdoctoral fellowship at the National Center for Atmospheric Research in Boulder, CO, he shifted his focus to turbulence and transport in the environment, using numerical simulations as a tool for understanding complex behavior in nature.

Summary of Activities/Interests

Dr. Richter's group is interested in computational techniques such as direct numerical simulation and large eddy simulation for studying turbulence in the atmosphere and ocean.  In particular, turbulent exchange of heat, moisture, and momentum at the air-sea interface is an area where detailed knowledge of these processes is critical for accurate storm prediction. Dr. Richter is also interested in developing tools for simulating multiphase systems that can be applied to a wide variety of geophysical flows including subsurface sediment transport and saltation.
