Research Interest

Research interests include Quantum Turbulence and High Energy Densified Propellants. These are funded by the Research Corporation and NASA, respectively. In Quantum Turbulence we wish to discover the mechanisms by which turbulent energy dissipates even though there is no viscosity, as in a normal fluid. This is done at 20 mK using micro-thermistors which we are also developing. The HEDMs are studied using Infrared Spectroscopy to measure chemical species and binding energies at 4 K.
