Research:

My research interests include physics of sound and vibration, sound in porous media, sound in inert gas - vapor mixtures, thermoacoustics, aeroacoustics, and infrasound. Working with undergraduates to develop a research project that expands their capabilities is very important to me. Link to a pdf of my current C.V. is here.
