Research interests lie in experimental particle physics. Presently, our group is part of the L3 collaboration at the LEP storage ring at CERN, Geneva. For this experiment, we have designed and constructed a Bismuth Germanate (BGO) forward-backward calorimeter which is used for luminosity and two photon physics measurements. Standard Model parameters have been deduced from precision measurements of the Z0 mass, total width, and partial widths into electron, muon and tau pairs. Limits on the Higgs mass have been set. The group will participate in the CMS detector development for the LHC at CERN.
