I serve as Deputy Spokesperson of the Large Synoptic Survey Telescope (LSST) Dark Energy Science Collaboration (DESC). We will measure the gravitational lensing and clustering of billions of galaxies to probe dark energy, modified gravity, dark matter, neutrino masses, and the inflationary potential starting in 2022. I am also a member of the LSST Galaxies science collaboration and the CANDELS and LESS collaborations.

The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) will discover 600,000 Lyman Alpha Emitting (LAE) galaxies from 2017-2020 and will use them to test the concordance cosmological model of general relativity plus a cosmological constant and cold dark matter. The HETDEX LAE sample will also revolutionize our understanding of galaxy formation via an order of magnitude improvement in precision measurements of the clustering of distant galaxies. I joined HETDEX in 2009.

The LADUMA survey will be performed on the South African SKA precursor radio interferometer, MeerKAT. I serve on the Executive Committee for LADUMA.

From 2003-2016, I served as PI of MUSYC, which is a square degree UBVRIzJHK survey plus satellite coverage from Chandra, XMM, HST-ACS, and Spitzer-IRAC+MIPS and spectroscopic follow-up using Magellan, Gemini, and VLT. Our deep images of the high-redshift universe reveal Lyman Alpha Emitters, Lyman Break Galaxies, Active Galactic Nuclei, Distant Red Galaxies and Damped Lyman alpha Absorbers, which represent families of galaxies selected in different ways. Measuring the star formation rates, stellar masses, ages and dark matter masses of these galaxies determines the extent to which the different types overlap and whether they constitute an evolutionary sequence fundamental to the process of galaxy formation. MUSYC has published 60 refereed papers, including several major advances in the study of galaxy formation and evolution. I led the discovery that Lyman Alpha Emitters represent progenitors of present-day L* galaxies, observed during an early starburst phase when they had low stellar mass, no measurable dust, and very high specific star formation rates.

From 2011-2013, I chaired the National Optical Astronomy Observatory (NOAO) Users Committee; the UC is always open to feedback from members of the community.

In Fall 2016, I taught Physics 689: Graduate Seminar on Astrophysical Data Analysis. Previously, I was the instructor for Interdisciplinary Honors Seminars 293: The Science of Science Fiction in Spring 2016, Physics 610: Graduate Interstellar Matter in Fall 2015, Physics 608: Graduate Cosmology in Spring 2017, Spring 2015 and Spring 2009, Physics 341: Principles of Astrophysics (I) and Physics 342: Principles of Astrophysics (II) during 2011-2014, Physics 110: Astronomy and Cosmology (Stars, Galaxies and the Universe) in Fall 2010, Fall 2009, Spring 2008, and Fall 2007, and Physics 689: Graduate Seminar on Galaxy Formation in Fall 2009.

I have also worked on the Extragalactic Atlas of the Digital Universe project at the Hayden Planetarium, where I served as a Hayden Associate from 2007-2011.

My research group at Rutgers includes undergraduates Nakul Gangolli and Jioayue Yuan, graduate students Humna Awan, Kartheik Iyer, Jean Walker Soler and Alejandra Muñoz, and research scientist Dr. Peter Kurczynski. Former group members and their current institutions are:

From 2002-2006, I was an NSF Astronomy & Astrophysics Postdoctoral Fellow in the Yale Center for Astronomy & Astrophysics. From 2002-2004, I was also an Andes Prize Fellow, which is a joint appointment at the Departamento de Astronomia of Universidad de Chile and the Astronomy Department at Yale University.

I wrote a public IDL code called observable that calculates the airmass, parallactic angle, and atmospheric differential refraction for use in planning imaging and multislit spectroscopy.

From 1999-2002, I was a postdoctoral research physicist at the Center for Astrophysics and Space Sciences at the University of California at San Diego. My research at U.C. San Diego involved an empirical study of galaxy formation in collaboration with Art Wolfe, Jason Prochaska, and Jeff Cooke. We performed multislit observations with the Keck telescope to find Lyman-break galaxies near known Damped Lyman-alpha Absorption Systems. This allowed us to study the emission properties of the DLAs as well as whether they cluster with emission-selected high-redshift galaxies. Our results were published in ApJ.

I received my doctorate in theoretical cosmology from U.C. Berkeley in May 1999. My dissertation with Professor Joseph Silk, Big Bang Leftovers in the Microwave: Cosmology with the Cosmic Microwave Background Radiation, is available here. Joe Silk and I also wrote a review article on the Cosmic Microwave Background radiation.

I led the WOMBAT project to estimate the Galactic and extragalactic foreground contribution to microwave anisotropy. Extragalactic foregrounds will significantly affect the MAP and Planck satellites, balloon-borne experiments such as MAXIMA and BOOMERANG, and interferometers including VSA, CBI, and DASI because of their high resolution.

I lectured Astronomy 10 at U.C. Berkeley during Summer 1999.
