Appearing next month in the NASA Alumni Newsletter. Walking on the Washington, D.C. Mall is an inspiring experience for all citizens. One might be inspired by the many memories and great institutions of our American people. Nestled as one of the most visited museums of the world is the National Air and Space Museum, just …

Abstract: Hypersonic flight-vehicles create shock and expansion waves that propagate through the atmosphere and are observed on the ground as sonic booms. We present a methodology to predict the near-field aerodynamic pressure and sonic boom signature using approximately 1% of the computational cost relative to fully-nonlinear computational fluid dynamics and state-ofthe-art sonic boom propagation solvers. …

It is more rare to be inspired as time goes on. On occasion, it is a great priveledge to hear a seminar by a world expert in turbulence. In this case at University of Florida, we had Professor Said Elghobashi from University of California Irvine join us for department seminar. He can be credited with …

Would you like to know the best possible method for solving a Syzygy problem? It is this. Having ascertained from your doctor that you are in a state of health to bear, without risk, severe brainwork and keen intellectual excitement, from the most candid of your intimate friends that you are in a pleasant temper, …
My graduate student, Alex Carr, defended his dissertation on sonic boom through the turbulent atmosphere. Title: SONIC BOOM PROPAGATION IN THE TURBULENT ATMOSPHERIC BOUNDARY LAYER Abstract: Sonic boom waveforms measured at ground level exhibit variability due to scattering and diffraction caused by the presence of turbulence in the atmospheric boundary layer (ABL). Sonic boom propagation …

This week I received tenure and promotion to Associate Professor of Mechanical and Aerospace Engineering at the University of Florida. It is a privilege to research, teach, and perform service here. I’m looking forward to many more years of working with wonderful colleagues and friends. The best part of the work has been helping my …
