Research Interests

Most broadly, my research interests fall into the category of cosmology or particle astrophysics. Measurements made so far using various astronomical techniques (i.e. infra-red, optical, x-ray) have led to the construction of a specific cosmological model which describes the evolution of structures such as the galaxies we see over time. This model requires the existence of a subatomic particle (referred to as Dark Matter or WIMPs) that has yet to be observed in the laboratory. As spokesperson of the SuperCDMS collaboration,

I am involved in the design and construction of the SuperCDMS SNOLAB experiment (in collaboration with an international team of scientists) at the SNOLAB underground facility in Canada. The experiment experiment is expected to produce world leading results in dark matter searches and has the potential to observe such particles or rule out classes of theoretical candidates.

Consideration of future dark matter search techniques have led to a parallel research effort, in collaboration with three other physics faculty members at UF, focusing on the use of superfluid liquid helium as a detection medium for light dark matter candidates. This approach makes use of nano electro-mechanical system oscillators with extremely high force sensitivity as sensors for dark matter interactions in the superfluid liquid helium.
