Research interests


I'm a Kavli Fellow at the Kavli Institute for Particle Astrophysics and Cosmology (Stanford University and SLAC National Accelerator Laboratory). My research interests include gamma-ray astronomy and neutrino astronomy. I'm currently working on gamma-ray astronomy and cosmic-ray electron and positron measurements with the Fermi Gamma-ray Space Telescope, and on camera electronics (using the TARGET digitizer chip) for the Cherenkov Telescope Array, a future imaging atmospheric Cherenkov telescope array for ground-based very-high-energy gamma-ray astronomy.

I received my PhD from UC Berkeley in December 2009 for work on the IceCube neutrino telescope.  I focused on the South Pole Acoustic Test Setup (SPATS).  SPATS is an array of acoustic sensors and transmitters that we built and operated to measure the acoustic properties of South Pole ice.  The acoustic technique could be used to extend the high energy sensitivity of IceCube and detect GZK neutrinos.  With SPATS we measured the sound speed, noise level, background transients, and acoustic attenuation in South Pole ice.
