Research
VERITAS - the Very Energetic Radiation Imaging Telescope Array System.
My research spans a number of topics in the categories of experimental astroparticle physics and high-energy astrophysics. This includes several investigations into the nature and origin of very high energy (VHE) cosmic radiation, including gamma rays above 10 GeV and cosmic rays above 100 TeV. I am also interested in topics at the interface of cosmology and astroparticle physics, including studies of the propagation of VHE gamma rays through extragalactic photon fields. I currently am working on the following projects:

VERITAS - the Very Energetic Radiation Imaging Telescope Array System. This experiment comprises 4 12-meter imaging atmospheric Cerenkov telescopes designed to detect and measure gamma rays over an energy range of 50 GeV to 50 TeV. VERITAS is currently taking data while under construction in southern Arizona. Once complete in 2007, VERITAS will be the most sensitive instrument of its kind in the northern hemisphere for the investigation of gamma ray sources such as galactic supernova remnants and AGN.

TRICE - the Track-Imaging Cerenkov Detector. TRICE is a collaboration with Argonne National Laboratory to build a high-resolution imaging telescope for the measurement of Cerenkov light directly from heavy cosmic ray primaries in the atmosphere. This technique was originated at Chicago and the first measurements demonstrating the method were performed in 2006, allowing the determination of cosmic ray composition with unprecedented precision for a ground-based instrument. Additionally, the technology developed for this task will have direct applications for the next-generation of ground-based gamma ray instruments.

Balloon and Space-based Transition Radiation Detection. Transition radiation detectors provide perhaps the only feasible way to make detailed measurements of high-energy (E > 100 TeV) cosmic ray fluxes at the top of the atmosphere. The TRD group at Chicago, which includes Professors Muller and Swordy, has recently flown two successful Long-Duration Balloon missions at the South Pole with the TRACER and CREAM instruments. In addition to this, we are working on designs for a possible future space-based TRD mission called ACCESS. ACCESS will be the largest cosmic-ray detector ever flown in space, allowing it to investigate energies up to the so-called "knee" in the primary cosmic ray spectrum.
