Erin M. O'Malley
PhD Student in Physics and Astronomy
I am fourth year graduate student and Ph.D. Candidate in the Department of Physics and Astronomy at Dartmouth College and an NSF Graduate Research Fellowship Program (GRFP) Fellow. I work with Brian Chaboyer (Dartmouth) and Andrew McWilliam (Carnegie Institute) on research in stellar astrophysics, measuring abundances and determining precise ages for metal poor stars in the Milky Way. I have obtained accurate abundance measurements for several unevolved low-metallicity stars, a crucial step in calibrating stellar evolution models for low-metallicity stars that can be used to age date globular clusters and I am currently testing the robustness of these models at such low metallicities. My thesis will focus on using high resolution spectroscopy and a differential chemical abundance analysis to better understand the star-to-star variations and chemical evolution processes evident in globular clusters (GCs) with multiple stellar populations.
Last year I was also the 2014-2015 Graduate Student Council (GSC) President. The goal of the GSC is to develop and enhance a sense of community across Dartmouth's graduate departments, programs and schools. I have participated in the GSC since I arrived at Dartmouth in 2012 and will continue to be an active member throughout my time at Dartmouth. I believe strongly the strong sense of community students feel at Dartmouth can greatly impact their success by providing the unconditional support from one's peers everyone in graduate schools needs.
