My research area is experimental particle physics. I have worked on a number of colliding beam detectors over the years at the MEA detector at ADONE (e+e-), BSS at ISR(pp), the HRS detector at PEP (e+e-), Mark2 at SLC(e+e-), SDC on SSC(pp), OPAL at LEP(e+e-) and ATLAS at LHC(pp). One of my hardware areas has been tracking detectors and, in particular, vertexing chambers using straw drift tubes.

I am currently working on the ATLAS detector at CERN. This detector will begin taking data in 2007, when the Large Hadron Collider (LHC) comes in to operation at CERN. Our group at Indiana University is building the barrel transition radiation tracker for this detector.
