Research Interests

The CMS Experiment ☆ We have recently filled our open postdoc position with the CMS experiment. The Large Hadron Collider began operations in 2008, with proton-proton collisions at 7 TeV center-of-mass energy in 2011, 8 TeV in 2012, and has operated at 13 TeV since 2015. These data allowed the direct observation of Higgs boson production in 2012. We have analyzed these data to search for new physics manifested by long-lived particles decaying to leptons and to perform tests of Standard Model processes using Drell-Yan production of muons. We are currently studying the properties of bottom hadrons, produced in the decays of top quarks.

CMS Detector Upgrades Purdue is leading the US effort to produce approximately 3000 pixel sensor modules with which to construct parts of the CMS tracking detector upgrade. We need to build a new inner tracking detector to allow efficient operation of the CMS experiment when the High-Luminosity LHC accelerator upgrades are completed. Purdue receives flex circuits and custom ASIC readout chips bump bonded to rad-hard pixel sensors, and developed a process for assembling these components using a precision robotic gantry, custom mechanical fixtures and tooling, and automatic wire bonding. Purdue completed the assembly of components needed for the Phase-1 CMS tracker upgrade in 2016, using a similar robotic assembly process to build these modules. The Phase-1 Forward Pixel Detector was assembled at Fermilab and now operates in the CMS detector at CERN. In collaboration with Fermilab, we have constructed a silicon strip telescope for use at the Fermilab Test Beam Facility with which to characterize rad-hard pixel sensors for future upgrades of the CMS tracker and other novel sensor technologies.

Charged Lepton Flavor Violation with Mu2e The Mu2e experiment will search for charged lepton flavor violation by stopping muons on an aluminum target and searching for μ→e. This rare process is sensitive to possible new physics at mass scales up to 104 TeV, well beyond those directly accessible at the LHC. Purdue is collaborating in the construction of the extinction monitor system, which will measure the time structure of the proton beam arriving at the muon production target. The detector uses pixel sensors and readout chips originally developed by the ATLAS experiment, and is responsible for the design and implementation of the associated data acquisition system. The DAQ system is implemented in programmable logic using commercial modules in a MicroTCA form factor.

Heavy flavor physics at CDF The CDF experiment operated at the Fermilab Tevatron from 2001 to 2012. This experiment pioneered the use at hadron colliders of hardware triggers for selecting decays of hadrons containing bottom quarks which made possible the first unambiguous observation of Bs oscillations. More recently, we measured the angular distribution of muons produced in the decays of Υ mesons which was thought to provide information about different quarkonium production mechanisms.

Education and Outreach I help organize a QuarkNet summer workshop for high school teachers as part of the Physics Department's outreach program. We provide support for participating teachers throughout the year, including an annual MasterClass activity for high school students, and local support for cosmic ray detector experiments in Indiana high schools. The 2016 QuarkNet workshop will be held during the week of June 27th-July 1st.

Other activities

I have also worked with the OPAL experiment at CERN, and the SLD detector at SLAC.
