I am a physicist, doing research in elementary particle physics, based in the Computing Division at Fermilab.

Since September 2008 my main research interest has been the development of a new experiment, Mu2e, to search for neutrinoless muon to electron conversion in the field of an atomic nucleus. Although this experiment uses relatively low energy particle beams, it's exquisite sensitivity to a very, very rare process provides access to mass scales far beyond the reach of even the Large Hadron Collider at CERN. The design of the Mu2e experiment starts from that of the MECO experiment, originally proposed for the Brookhaven National Laboratory, and will evolve as we update the design with new technologies that have emerged since the design of MECO. An experiment to search for muon to electron conversion was called out as a high priority by the 2007 P5 Panel and received Stage I approval from the Fermilab PAC in November 2008.

My previous physics projects at Fermilab were on the BTeV, FOCUS and SiD experiments. BTeV was an R&D effort to design a dedicated B-physics experiment to be located at the Fermilab Collider in the late Run II era. The experiment was to be the first of the second generation of B-factories, designed to explore the CP violating phenomena which are predicted to occur in the decays of hadrons containing b quarks. Unfortunately, just at the cusp of final approval and funding, BTeV was canceled by the Department of Energy.

The FOCUS experiment is a forward spectrometer which detects charmed hadrons produced in photon-nucleon interactions. This is a high statistics experiment which has over 10 times the data of its predecessor, E687. The physics analysis of the 1996/97 data set is nearly complete. Out publications cover doubly Cabbibo suppressed decays and D0/D0bar mixing, Dalitz plot studies, semi-leptonic decays, lifetime studies, charmed spectroscopy and searches for rare decays, including those that are forbiden in the Standard Model.

For a short time I collaborated on the design of the SiD detector for the proposed International Linear Collider.

While at Fermilab I have also worked on the development of improved beam position monitors for the Tevatron and for the Main Injector. These projects led to significant operational improvements of the respective accelerators.

Before coming to Fermilab, I worked on the ARGUS experiment at DESY, in Hamburg, Germany, and on the CLEO experiment at Cornell University.
