I am a research scientist with the NASA/JPL Spitzer Science Center at the California Institute of Technology where I study the formation and evolution of structure in the universe.  I am currently focusing on detailed studies of the first galaxies and structures at z>4 and the formation of the Hubble sequence at z<2.  I have made significant contributions to the COSMOS and GOODS Legacy projects. This includes deep imaging of The Hawaii Hubble Deep Field North.  I am also a co-organizer of the PHAT project aimed at developing a set of best practices for photometric redshifts.
