Research Interests:

Research in my low temperature laboratory involves quantum fluids and solids, superfluidity, and porous media.

We are currently focused on the unusual "supersolid" behavior of helium crystals at very low temperatures, using a combination of elastic/acoustic and thermodynamic techniques.
