Research Summary

I study the properties of ultrahigh energy cosmic rays (UHECR). I was a senior member (and acting PI of the Utah group) of the High Resolution Fly's Eye (HiRes) Experiment. The HiRes group published the first observation of the GZK Cut-off in the cosmic ray spectrum predicted in 1965. My analysis of HiRes data was the primary contribution to this discovery. Currently I am co_PI of the Utah group on the Telescope Array (TA) experiment, continuing the study of UHECR with upgraded detectors.
