Welcome to my homepage at Macalester College!
ATTENTION! During the 2007-2008 acedemic year I will be a visiting professor at the University of Wisconsin at Oshkosh.|

My research interests lie in studying the stellar populations of globular clusters and dwarf galaxies. By understanding their stellar populations, we may gain a better understanding of the way our Milky Way has formed. The research I do focuses on the use of variable stars to probe properties such as age, metallicity, and distances in these systems. I have also used high-resolution stellar spectroscopy to examine the chemical evolution of stars in globular clusters and dwarf galaxies.
In the spring 2007 semester I taught two courses: Astrophysics (PHYS 460) and Principles of Physics I (PHYS 226).
In the Summer of 2004, I began a program to use the Macalester
Observatory to study the Population II Cepheids in globular clusters. This
program is being conducted by myself and the summer REU student Reid Lustig in
conjuction with Michigan State University and Central Michigan University. The
goal of the project is to determine accurate periods and magnitudes for these
stars to improve their use as distance indicators. The main web page for the
program at Macalester College can be found here.
