DEEP is my major research area involving
Keck observations of faint galaxies. Several pilot redshift surveys totaling
over 1000 galaxies to I ~ 24 are now complete as part of DEEP1.
The main phase of DEEP , called DEEP2,
is also now finished. DEEP2 used over 90 Keck nights
with a powerful instrument (DEIMOS)
to secure about 40,000 galaxies at redshifts z ~ 1. Such a
large sample is needed to probe the large scale structure of galaxies and
unravel the details and physical mechanisms involved in galaxy formation
and evolution. In one of the 4 regions of the DEEP2 survey,
known as the Extended Groth Strip (EGS), a consortium of teams known
added a suite of deep to very deep panchromatic data ranging from the
to radio. These data allow powerful probes of distant Active Galactic
(AGN) with supermassive black holes, as well as luminous, dusty
galaxies. In this region, another 10,000 galaxies was observed with
DEIMOS as part of DEEP3 and completed in 2011. Current and future plans include follow-up
multi-object near-infrared spectroscopy with the newly operational MOSFIRE instrument on Keck.
CfA0 , the Center for Adaptive
Optics, was an NSF Science and Technology Center
from 2001-2010 and had its headquarters located at the University of California, Santa
Cruz. As one of its founding members, some of my research involved
the use of adaptive optics to obtain high spatial
resolution studies in the near-infrared of extragalactic sources. The CfAO Treasury Survey
(CATS) combined HST images with AO images and spectra in the near-IR to
study distant galaxies, AGN, supernovae, gravitational lenses, etc.
multi-wavelength research as part of AEGIS has recently expanded to
include 4 of the other best observed fields for faint multi-wavelength
extragalactic research: GOODS-North and GOODS-South, an UltraVISTA portion of COSMOS, and the central part of the UKIDSS Ultra-Deep Survey (UDS)
fields. I am a senior member of two surveys
that have now solidified these 5 as the very best legacy fields for the
foreseeable future: one led by G. Fazio (CfA) is finished and gathered 2100 hours
of Spitzer IRAC data (SEDS) and the other, completed in August 2013, a 902 orbit survey using HST WFC3 near-IR and a 902 ACS images survey (CANDELS) as part of the HST Multi-cycle Treasury Program.

We filled one postdoctoral scholar position for 3 years starting
fall 2013; we expect no new openings before fall 2015 and will advertise
any such openings in the AAS Job Register.
