This fellowship provides recent graduates (within the past two years) opportunities to work on the experimental research program of the Physics Division, including high-energy collider physics; direct dark matter searches; cosmology using Type Ia Supernovae, baryon acoustic oscillations, and the cosmic microwave background; rare decay experiments; and neutrino physics. In all these areas the Physics Division follows a long tradition of advanced detector development as well as data analysis. As employees of Berkeley Lab, Chamberlain fellows work in a research environment synonymous with scientific excellence. Thirteen Nobel Prizes are associated with Berkeley Lab, 8 of them in physics. The Fellowship honors Owen Chamberlain (Nobel Prize 1959), who, together with Emilio Segre, Clyde Wiegand, and Thomas Ypsilantis, discovered the anti-proton at the Berkeley Bevatron in 1955. Berkeley Lab is a truly multidisciplinary environment, with sixteen scientific divisions in addition to Physics, and extensive ties with the adjacent University of California, Berkeley including many centers and activities (for example BCG and BEPP. Berkeley Lab divisions include Accelerator Technology and Applied Physics, Nuclear Science, Engineering, Computational Research, Scientific Networking, and the National Energy Research Scientific Computing Center.
