• GEMS (Galaxy Evolution From Morphology And SEDs): One of the first large (900 arcmin^2) contiguous field imaged with HST ACS in 2 filters (F606W) and F850LP). GEMS provides HST-based morphologies and accurate redshfits from COMBO-17 for 9,000 galaxies down to R<24 in the range z~0.2-1.2. Panchromatic coverage is provided by Spitzer, Chandra, and GALEX.

• GOODS (Great Observatories Origins Deep Survey): GOODS unites extremely deep observations from Spitzer Hubble, and Chandra, ESA's XMM-Newton.

• STAGES (Space Telescope Abell 901/902 Galaxy Evolution Survey): A multiwavelength survey to probe the physical drivers of galaxy evolution in dense environments, using HST (80 orbits; ACS F606W), Spitzer (MIPS +IRAC), GALEX (FUV,NUV), Chandra XMM-Newton, COMBO-17 spectro-photometric redshifts, and gravitational lensing mass maps.

• The HST ACS Treasury Survey of the Coma Cluster: This Treasury survey was allocated 164 HST orbits in Cycle 15 to map Coma, the richest galaxy cluster in the local Universe. Complementary Spitzer, GALEX,Chandra, and ground-based data are also available.

• The GOODS-NICMOS Survey of Massive Galaxies at z=1.7 to 3

• The VIRUS-P Exploration of Nearby Galaxies (VENGA): conducted with 150 nights using the Mitchell Spectrograph on the 2.7m telescope at McDonald Observatory.

• SHELA-HETDEX study of galaxy evolution as a function of time (z~ 2-4) and environment using 0.8 million massive galaxies, five large photometric surveys (DECam ugriz, NEWFIRM K-band, Spitzer IRAC, Herschel-SPIRE, XMM X-ray) and the ongoing HETDEX spectroscopic survey.
  
  Research highlights: Some key results from my group include: (a) While earlier work suggested a dearth of barred galaxies at earlier times, we were the first to demonstrate that strong stellar bars are common in massive disk galaxies over the last eight billion years, a period long enough for bars to drive significant secular evolution of galaxies (Jogee et al. 2004); (b) We showed that contrary to common lore, only at most 30% of the cosmic star formation rate density can be assigned to visible major mergers over half of the age of the Universe. We also set the first empirical constraints on the minor merger rate of galaxies over that epoch (Jogee et al. 2009); (c) We found that when the Universe was merely a few billion years old, the majority (>60%) of massive galaxies were disk-dominated and over a third were ultra-compact (Weinzirl, Jogee et al. 2011). This result poses serious challenges to current state-of-the-art theoretical models. (d) Using a sample of massive galaxies from SHELA/HETDEX that is an order of magnitude larger than other studies to date, we robustly measure the high-mass end of the stellar mass function of star-forming galaxies at 1.5 < z <3.5 and stress-test theoretical models of galaxy formation. Predictions from IllustrisTNG 300 hydrodynamical simulations agree within a factor of a few with our results, but three semi-analytic models (SAMS) -- SAG, SAGE, GALACTICUS -- with different AGN feedback modes underestimate the number density of massive galaxies by up to a factor of 1000. This suggests that the physics of galaxy evolution and/or its sub-grid implementation need to be revisited in the SAMS. (Sherman Jogee, Florez et al. 2019, submitted). Please see my CV for details and contact me for a list of current projects for graduate students.
  
  

  The Hubble Ultra Deep Field (HUDF), the deepest visible-light image ever made of the Universe, (Credit: NASA, ESA, S Beckwith and HUDF home team ) shows the first galaxies to emerge from the so-called "dark ages," (the time shortly after the big bang when the first stars reheated the cold, dark universe), and chronicles a period when the universe was younger and more chaotic, with violent interactions between galaxies.
