As of August 2015, I have worked with Kristian Finlator to explore the use of aligned metal absorbers to measure the ultraviolet background at high redshift.

I completed a B.S. degree in 2014 after double majoring in physics and astronomy at the University of Washington, Seattle. During this time I assisted with assembly and coding for the Axion Dark Matter eXperiment (ADMX) at the Center for Experimental Nuclear Physics and Astrophysics at UW. Switching gears to the realm of astronomy, I collected and analyzed photometric data of candidate symbiotic stars with Julie Lutz to catalog their variability. I also observed globular clusters under the supervision of Dr. George Wallerstein to ascertain the viability of using photometric filters to measure stellar metallicity.
