Professor Smith's research interests are in experimental high energy physics. As a member of the CLEO collaboration (Cornell), he was a primary author of several measurements of rare B meson decays. Among these was the first observation of the decays B -> pipi and B -> Kpi, which are crucial for CP violation measurements at B Factories, and the discovery of the decay B->eta'K with a rate much larger than had been expected. Until 2010 he was involved in the BaBar experiment, running at the SLAC B-Factory PEP II. The premier result in 2001 was the first observation of CP violation in B decays and first significant measurement of the quantity sin 2beta. A measurement of significant CP violation in the decay eta'K0 was published in 2006 and improved in 2009. A difference between the value of sin 2beta in the two measurements would be a signal of physics beyond the Standard Model. He is now involed in the CMS experiment at the Large Hadron Colllider (LHC) at CERN, searching for evidence of supersymmetric particles.
