Research Interests

Current
CDF, collisions at the Collider Detector at Fermilab, including search for Supersymmetric (SUSY) particles.

Design, construction and calibration of the CDF Run II scintillating tile-fiber Endplug Calorimeter, including early discovery of wavelength shifting fiber patterns with excellent response uniformity over the entire scintillating tile, and demonstration of precision calorimeter calibration using moving radioactive sources.

Design, construction and calibration of the CMS Hadron Calorimeters, to probe beyond the Standard Model, including Higgs and SUSY particle searches, with 14 TeV pp collisions at the CERN Large Hadron Collider.

Design R&D for gas Cherenkov calorimeters for use at Next Linear Collider and for possible ultra-high-luminosity "Super LHC" at CERN.

Characterization and development of SiPM (Silicon Photomultiplier) devices for use in High Energy Physics detectors.

Previous
Experimental High Energy Particle Physics while a member of the Purdue Physics faculty:
Fixed target Charmonium production at Fermilab
Weak charged and neutral current Neutrino interactions at Argonne and Fermilab, (including first observation of neutral currents in single pion production)
