Most of my past and current research has been in the general area of particle astrophysics, with an emphasis on high energy cosmic rays and gamma-ray astronomy. My research has involved balloon, spacecraft, and ground-based detector systems investigating galactic and extragalactic radiation from hard X-rays to gamma-ray energies.
In 2001 I ventured into the field of cosmology and joined - together with other scientists from the University of Michigan - the SNAP collaboration. The primary science goal of the SNAP mission is the identification of the dark energy which is believed to drive the acceleration of the universe.
I am also involved in the CREST project and am still mining the HEAT-pbar
data (check out the pictures from the HEAT-pbar balloon campaigns in 1999 and
2001 below).
