My research centers on non-accelerator particle physics, particle astrophysics, and low temperature physics. In particular, my work is on the development, construction, and operation of new detectors using liquefied noble gases, which are useful in looking for physics beyond the Standard Model. Applications include the search for dark matter interactions with ordinary matter, searches for neutrinoless double beta decay, and the measurement of the low energy solar neutrino flux. I am especially interested in the physics of the response of liquefied noble gases to particle interactions, the calibration of these detectors so as to understand their response, and the overall development of new experimental techniques for reaching sensitivity to extremely rare, low-energy particle interactions. Other interests include the use of liquid xenon for gamma-ray imaging, and the visualization of turbulence in superfluid helium.
