Summary

I am working on the discovery of dark matter using cryogenic semiconductor detectors as a member of the SuperCDMS experimental collaboration. Currently, I am leading the drive to use simulations of our detectors to model data collected in the experimental run at Soudan, Minnesota. Without a model of the various sources of experimental backgrounds, we can only set upper limits on the presence of dark matter. To discover it, these simulations are crucial.

In order to prepare for the next experimental run, I am leading the development of a new trigger system. This trigger system will significantly expand our ability to see low-mass dark matter by improving sensitivity to low-energy interactions in our detectors.

In a post-discovery era, I plan to measure the properties of dark matter and to search for WIMPs that are not part of the Milky Way galaxy's thermalized dark matter halo. I hope to observe astrophysical and cosmological sources of such non-thermal WIMPs, effectively creating a new field of dark matter astronomy.

In the past, I have studied the top quark and the Higgs boson using data from the Collider Detector at Fermilab (CDF). I performed the first published search for the associated production of the Higgs boson and top quarks. I also made significant advances in the study of the top-quark forward-backward asymmetry, a fascinating measurement that displayed an intriguing anomaly at the Tevatron. My work on the top quark led to my appointment as co-convener of the Top and Beyond the Standard Model physics group, an international leadership position in which I have been responsible for the scientific content of a large and active segment of the CDF collaboration.
