I am an Assistant Research Professor at University of Arizona and a member of the James Webb Space Telescope (JWST) NIRCam instrument and science teams. I study galaxy evolution in the very early Universe. I'm interested in many aspects of how galaxies form and evolve, but I am particularly interested in the early evolution of massive galaxies that no longer form stars. After JWST launch, I will be leading two JWST Cycle 1 surveys as Principal Investigator to address these questions (see Research page).

Prior to joining the faculty at Arizona, I was a National Science Foundation (NSF) Astronomy & Astrophsyics Postdoctoral Fellow at the University of Arizona. As an NSF Fellow, I lead a deep survey using the Atacama Large Millimeter/submillimeter Array (ALMA) to study why massive galaxies stop forming stars.

I did my PhD at UMass-Amherst, working with Mauro Giavalisco and the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) collaboration. My work focused on the formation of compact star-forming galaxies, rare dense galaxies that are thought to become the first quenched galaxies in the Universe. I started my PhD working in sub-millimeter astronomy with the AzTEC bolometer array, on the Atacama Submillimeter Telescope Experiment (ASTE) in Chile. My work on the formation of quenched galaxies now spans the electromagnetic spectrum, from X-ray to radio wavelengths.

Before starting graduate school in Astronomy, I lived several years in Alaska studying Arctic geophysics and exploring the wilderness of the far North.
