Research Interests
David Williams is a member of the Milagro and STACEE collaborations, pursuing the study of high-energy gamma-rays from astrophysical objects. He is particularly interested in understanding the nature of gamma-ray bursts and the high-energy emission mechanism of active galactic nuclei. He has been an active participant both in the development of the instrumentation for the experiments, especially the electronics, and in the analysis and interpretation of the data.
