Current Research

Turbulent flows with variations of density arise in many different areas of science and technology. Combustion of the fuel in a car engine, urban air pollution/smog, convection in stellar interiors, and a draft of cold air from a window are but a few examples. My research seeks to improve our physical understanding of and computational algorithms for turbulent mixing in accelerated variable-density shear flows. Here are a few samples of my current research.

Writings on Energy, Physics and Society

Detailed lectures notes on turbulence and computing with annotated references:

A few short articles on energy, physics and society that I wrote are posted on-line at the Stanford PH240 and PH241 websites. Below I've posted links to those articles along with a brief excerpt. I enjoyed writing and learning about these topics and hope to post more writing samples in the future.
