About Me

I'm currently a Ph. D. student and NSF Graduate Research Fellow at Steward Observatory, University of Arizona working with Professor Marcia Rieke and NASA's James Webb Space Telescope Near-IR Camera (NIRCam) team. My research uses the Universe as a time machine to tell the story of how galaxies evolve over cosmic time. More specifically, I use observations of galaxies to study their star formation and chemical enrichment histories.


See below for information on some projects I have worked on.

Figure: HST/ACS images of our sample of passive field galaxies. We compared these field galaxies to cluster galaxies at similar redshifts. Our results may indicate that the environment causes differences in the stellar populations of bulge-dominated galaxies. See below for a link to the publication about this research.

I aided in the search for the electromagnetic counterpart to gravitational wave events by optimizing the search algorithm that combs through Fermi data looking for gamma-ray bursts.
