I am a member of the VERITAS and CTA collaborations, pursuing the study of high-energy gamma-rays from astrophysical objects. These experiments adapt experimental techniques developed for particle physics to explore outstanding problems in high-energy astrophysics and gamma-ray astronomy. I am particularly interested in understanding the nature of gamma-ray bursts and the high-energy emission mechanism of active galactic nuclei. I participate in both the development of the instrumentation for the experiments, especially the electronics and photodetectors, and in the analysis and interpretation of the data. VERITAS is one of the premier instruments worldwide for observations of gamma rays above ~100 GeV. During the summer of 2012, we helped complete an upgrade of the cameras with higher sensitivity photomultiplier tubes. We have an active program of source observations and data analysis.
