About Me: I am currently a National Science Foundation Astronomy and Astrophysics Postdoctoral Fellow
working with UCLA researcher R. Michael Rich on determining the detailed chemical composition of the
Milky Way bulge via high resolution spectroscopy. In addition to working on the Galactic bulge, I also employ
the techniques of stellar spectroscopy to understanding the formation and evolution of globular clusters.
