Constraints on low-mass dark matter from CDMS-II and
the development of highly-multiplexed next-generation detectors

Abstract: Data from the Cryogenic Dark Matter Search (CDMS II) have been reanalyzed to give increased sensitivity to Weakly Interacting Massive Particles (WIMPs) with masses below 10 GeV/c^2.  Constraints on light WIMPs from an analysis of the CDMS II spectrum with a 2 keV recoil-energy threshold as well as a search for annual modulation in the observed low-energy event rate will be presented.  These results directly constrain low-mass WIMP interpretations of the potential signals reported by the DAMA/LIBRA, CoGeNT and CRESST experiments.  Progress developing radio-frequency multiplexed detectors for next-generation rare-event searches will also be discussed, including the first demonstration of energy and position-resolved phonon-mediated particle detection using microwave kinetic inductance detectors.

Biography: I am currently a graduate student at Caltech, working with Sunil Golwala on the Cryogenic Dark Matter Search (CDMS).
