I study the elastic properties of silicate glasses, experimental analogues for silicate melts, to interpret seismic anomalies in Earth's upper mantle. I use shockless dynamic compression, gigahertz ultrasonic interferometry, and various spectroscopy techniques to demonstrate the effects of pressure and volatile content on the seismic (sound) velocities and elastic moduli of silicate glasses. Much of this work is done with the assistance of collaborators at Sandia National Laboratories, Corning Incorporated, and Northwestern University.
