My simulation work includes propagation of cosmogenic muons through half a mile of greenstone and tracking of the associated electromagnetic and hadronic showers incident on a veto shield array in the Low Background Counting Facility at the Soudan Underground Laboratory. This helps benchmark the performance of a neutron multiplicity meter installed in the LBCF, which will be used to probe the neutron background at that depth. Any rare event search involving nuclear recoils requires a thorough understanding of this background, so it's also relevant for CDMS.

I've also run cosmogenic muon simulations for the proposed GEODM experiment at DUSEL, as well as simlations of both the gamma and neutron calibration for CDMS. Together these allow us to estimate the various backgrounds that will soon become more important. Our background estimates have long been dominated by the surface beta background, but the newly-installed iZIP detectors at Soudan should see this radically reduced.

My early analysis work was focused on the quality of phonon pulse fits. I also worked on using new combinations of timing parameters from the time-domain fits to make a multidimensional cut to reject electron recoil events on the surface of a detector that we might otherwise mistakenly identify as WIMPs.

More recently, I've been involved with the analysis of new data from the first Supertower installed at Soudan, containing next generation detectors with increased mass and improved discrimination properties. I produced the optimized 2D surface rejection cut after automating testing of many timing parameters.
