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. My main research interests are cosmic-ray antiparticles and cosmic-ray production, propagation and interactions and understanding the nature of dark energy, and how it can best be characterized using both space and ground based instruments.
I am a memebr of the JDEM/SNAP collaboration and the DES a>collaboration. The primary science goal of those experiments s the identification of the dark energy which is believed to drive the acceleration of the universe.
I am also part of the CREST project.
