Classes for Fall 2016

  • ASTR 1000: Introduction To The Universe
  • ASTR 4330: Observational Astrophysics

    I also teach an outdoor astronomy laboratory (ASTR 1210) class each semester. Every other year I also teach a senior level course on observational astrophysics (ASTR 4330) that gives students the opportunity to calibrate and analyze archival optical (imaging and spectroscopic) and radio interferometric data.


    Much of my research centers on multi-wavelength observational studies of star formation in strongly interacting systems in the low-z universe. Using data collected using the Very Large Array and the newly commissioned Atacama Large Millimeter Array in tandem with optical and infrared data, I try to better understand the processes by which galaxies convert their gas supply into stars, and conversely, the processes that act to switch-off or ``quench'' star formation on large scales in these same objects. In collaboration with Gordon Stacey's group at Cornell University, we are exploring the rate and evolution of star formation in the more distant universe using sub-millimeter spectroscopy with ZEUS-2. I am also interested in the nature of faint radio sources with exceedingly faint (or no) optical counterparts.

  • Millimeter and Submillimeter Studies of Galaxies
  • The Nature of Faint Radio Sources

    I seem to serve on a lot of committees lately. Here are a few from the past three years:
    - NRAO (GBT/VLA/VLBA) Science Review Panel (2012 - present)
    - NSF Extragalactic Panels
    - Departmental Astronomy position search committee (chair)
