My research has focused on precision studies of the properties of the W boson, tests of QCD using Z bosons, and searches for exotica particles predicted by theories of physics beyond the standard model.
The W and Z boson are the carriers of the weak force. While a member of the CDF collaboration, I contributed to the W mass measurement from the '88/'89 data. As a member of the D0 collaboration, using the run I data, my students and I did a measurement of the W and Z cross sections and an indirect measurement of the W width. Using Run II data, we did measurements of the W width, the Z rapidity distribution, the transverse momentum spectrum of the Z, the W mass, and developed a novel method for modeling the recoil in W decays. I have been convener of the CDF W/Z group and convener of the Dzero W mass group.
There are many reasons to think that the standard model can not be a complete theory of particles and their interactions. Many theories that go beyond the standard model predict new particles. My thesis was on a search for a fourth generation quark at TRISTAN. I was convener of the D0 New phenomena group during the time that the CDF "eegamma gamma" event and the HERA "leptoquark discovery" were all the rage. A MD student who worked with me wrote a paper on searching for squarks and gluinos in the jets plus missing ET channel. I was convener of the CMS Exotica group during 2007 and 2008. My current students are preparing searches for leptoquarks and heavy, and long-lived gluinos for the start of data taking at the LHC.
I am also interested in calorimeters, especially the reconstruction of jets and missing ET. I was the first CMS PRS jets and MET leader (1999-2002), and
I was chair of the review committee for the Dzero jet energy scale group at the
start of run II. I've also done work on detector simulation. I was head of the Dzero simulation group
for 2 years and wrote Dzero's fast simulation program. I worked on the D0 program
that allows real data zero bias events to be overlaid on simulated signal events.
I also worked for a while on the muon system of the D0 detector . I proposed a new scintillator-based muon system for the Dzero upgrade, built a prototype which was installed in the Run I detector for testing. The upgrade was approved for Run II and built. I also calculated albedo rates in the muon system using GEANT, using the simulation to design improved shielding, which was also included in the Run II detector.
On AMY, I designed, constructed, and installed the HV distribution system for the x-ray detector. I also worked with an engineer to design an amplifier that went between the preamp and the ADC.
I am a "Fellow" of the American Physical Society. I've served on many committees, like the FNAL program advisory committee ("PAC"), the federal high energy physics advisory panel (HEPAP), the executive committee of the APS division of particles and fields (DPF), and various review committees for NSF and DOE. I was US CMS Physics coordinator from 2002-2007. I was chair of the HEPAP "informal working group on the university program" during 2009. I was also co-leader (and co-founder) of the "LHC physics center" at Fermi National accelerator lab from 2004-2007. I was electroweak convener for CDF, New Phenomena convener for D0, and JET/MET, SUSYBSM and Exotica convener for CMS. I am current co-convener of the CMS group charged with reconstruction of missing transverse energy, the signature of the "dark matter" particle when produced in hadronic collisions.
