I teach courses in physics and astronomy, and always look forward to lively interactions with my students.

I arrived in Rice Lake a year after completing my Ph.D. at Iowa State University. During graduate school, I had the opportunity to spend six months working at the Infrared Processing and Analysis Center at Caltech in Pasadena, CA. I continue to work with collaborators there on a number of projects. My research interests are in the study of distant galaxies. I am particularly interested in collisions between galaxies, and how these collisions affect the way in which these galaxies form stars. I have used observations from several space-based observatories, including the Hubble Space Telescope, Spitzer Space Telescope, Herschel Space Observatory, and Chandra X-ray Observatory.
