He also finished some of the final spectral data reductions for data from the Hydra multifiber spectrometer at the CTIO 4-meter. He was basically just trying to understand how multifiber spectroscopy works and how the data is reduced.
  • Devin Kasper, Minnesota State University Moorhead, Class of 2011
    • Devin spent the summer of 2008 being a "line monkey" (his words) reducing data from the Hydra multifiber spectrometer at the CTIO 4-meter. His specific goal was to help develop the pipeline for reducing the stellar spectra to determine velocities of stars in the thick disk as related to our Thick Disk Asymmetry project. He went on to work at the National Solar Observatory REU the following summer and transferred to the University of Wisconsin Madison. Devin left academia and went on as an Engineer, eventually getting an MBA to Yale and becoming an associate at McKinsey & Company, a management consulting firm.

    • Josh and Laura spent the summer of 2006 reducing images taken at the Y4KCam on the 1.0-m at Cerro Tololo Inter-American Observatory in Chile. Specifically he worked with me to develop the software for reducing almost 1000 raw 16 megapixel images in four bandpasses (U, B, V, and R) and turning it into photometric information on all the stars in those images. Josh completed a post-doc in particle physics at Brown University and now works for Intel.
  • Wendy Bennett, Drake University, Class of 2006
    • Wendy was a volunteer researcher for me in the summer of 2004.  She spent one day a week working on extending Supreet Sidhu’s research by modifying her code to work the Sloan Digital Sky Survey Data Release 2. She has since obtained a Masters in astronomy at Iowa State University.
  • Supreet Sidhu, Swarthmore College, Class of 2005
    • Supreet spent the summer of 2003 examining the problem of determining the distribution of dust in external galaxies. This was done by obtaining isophotal magnitudes and diameters for ~90,000 galaxies in the Sloan Digital Sky Survey (Data Release 1). Analysis is ongoing, but her analysis of these observations showed the feasibility of a statistical determination of the level of internal extinction in external galaxies. She is now a college instructor at Washington College.
  • Megan B. Roscioli (now Megan B. Gralla), Haverford College, Class of 2005
    • Megan performed supervised research investigating the nature of the ISM of Low Surface Brightness galaxies and their distribution relative to Large-Scale Structure. This included making millimeter observations with the Kitt Peak 12 meter of several LSBs and radio observations at the Arecibo 305 meter. She reduced the data from these projects to publication quality. Megan was also a recipient of the prestigious Barry M. Goldwater Scholarship in Spring of 2003. She moved on to become a graduate student in astrophysics at the University of Chicago, getting her Ph.D. in 2011. She is currently a Senior Research Associate at the University of Arizona.
  • Martin Mudd, Williams College, Class of 2004
    • Marty was a summer student at Haverford in the summer of 2002. His research project focused on attempting to isolate stars tidally striped from globular clusters from foreground stars in the same field using the Minnesota Automated Plate Scanner Catalog of the POSS I. The project was not a “success” in that we discovered the color resolution of photographic plates was not sufficient to isolate the streams, but he did an excellent job in testing the concept. Marty went on to do Teach for America and current runs the Adventure Unschool in Kentucky.
