Christina C. Williams


I'm currently a postdoc at the University of Arizona, working with the James Webb Space Telescope Near-IR Camera (NIRCam) team. I recently completed my PhD in the Astronomy department at UMass Amherst, working with Mauro Giavalisco and the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) collaboration on galaxy evolution at high-redshift. Specifically, I am interested in what causes galaxies to quench their star-formation early in cosmic time. I also spent some time working in sub-millimeter astronomy with the AzTEC bolometer array, on the Atacama Submillimeter Telescope Experiment (ASTE). Please see my research page for details.
I came to UMass after studying Physics at Johns Hopkins University, where I was a member of the nearby and low-mass star research group in the department of physics and astronomy. I then moved on to do my masters in Geophysics at the University of Alaska, Fairbanks (UAF), where I studied tectonics in the Arctic Ocean. Specifically, the Alpha-Mendeleev Ridge, a large igneous province of ambiguous origin that cuts across the Amerasian side of the Arctic. I also worked as a research technician for the Sea Ice Research Group at the Geophysical Institute at UAF, where I worked on the coastal sea ice radars in Barrow, Alaska and Wales, Alaska. I also like to see the world (see photos page).
