COSMOS: Co-lead with S. Lilly (taking over leadership from N. Scoville as of June 2010), coordinating the efforts of over 150 researchers world wide, leading major North America based funding and observing proposals. I also lead the high-redshfit working group. I oversaw the observation, reduction, and archiving of all ground based optical and near-IR imaging for COSMOS including data from the CFHT, CTIO, LBT, Subaru, UH2.2m, and UKIRT. This involved coordination of 14 individuals at seven institutions, and developing software for new instruments such as WIRCAM on CFHT. I am also responsible for quality control on data products delivered to the general astronomical community.
PHAT: Co-lead of the PHotometric-redshift Accuracy Testing (PHAT http://phat.caltech.edu/) project with L. Moustakas and H. Hildebrandt. The goal of this project is to develop robust photometric redshifts for Dark Energy probes and all sky surveys. We are developing a quantitative testing methodology for Photometric Redshift techniques similar to the STEP project for weak lensing.
Spitzer Archive: Responsible for planning and implementation of a pipeline to produce science quality images and catalogs for all IRAC and MIPS data taken during the Spitzer Cryogenic mission. These data will be part of the Spitzer Heritage Archive. Duties involve working with a team of 15 or more scientists, data base managers and software engineers along with an oversight board to implement the software and quality analysis procedures.
Space: HST, Spitzer, Chandra, XMM, and Galex
Optical/IR: Extensive experience (over 200 nights) with both optical and IR imaging and spectroscopy including over 75 nights on the Subaru 8.3m telescope, over 30 nights on the Keck 10m telescope, and over 50 nights on the CFHT 3.6m, along with many more on the UH2.2m, UKIRT, Palomar, the CTIO 4m and the KPNO 4m.
Sub-mm: >20 shifts on JCMT with SCUBA, SCUBA-2 and Heterodyne spectrographs, 18 nights on CSO, queue observing totaling over 200h on SMA, PdBI and CARMA. Recently allocated time on ALMA.
Radio: Several programs on the E-VLA, and VLA totaling over 500, programs totaling more than 30h on the VLBA.
Commissioning: Member of the commissioning team for the Rockwell NGST detector test system (ULBCAM) on the UH2.2m telescope. This instrument was the first IR mosaic camera in operation and the first to use HAWAII-2 arrays.
Shared risk observer with SCUBA-2, Keck DEIMOS, UKIRT WFCAM, CFHT WIRCAM, CFHT Mega-Prime, Subaru Suprime-Cam, Subaru CISCO.
Development: CCAT, leadof the extragalactic science working group developing design specifications and proposals.
Euclid (DUNE), member of the proposal science team. Developed the science case, camera specifications, and photometric redshift requirements.
Software: Developed a pipeline that autonomously categorized, reduced, masked, and photometered all IRAC and MIPS Sptizer Cryogenic data. The system also performs automated QA on the resulting data.
Developed the algorithms and procedures used by Terapix for the first pass reduction (bias subtraction, flat fielding, cross talk correction) CFHT WIRCAM data.
Developed a reduction pipeline for mosaic CCD and IR instruments that uses parallel processing and I/O on computing clusters. Currently work with ACS, Suprime-Cam, Megaprime, CFHT-12K, WIRCAM, WFCAM, and ULBCAM data.
Time Allocation: Have been a memebr of the JVLA, Taiwanese CFHT, and University of Hawaii TAC.
Publication Referee: Referee for Nature, ApJ, ApJL, MNRAS and A&A.
