I analyze data from large-scale structure surveys, such as the Sloan Digital Sky Survey and the Dark Energy Survey. My research allows robust and precise measurements to be made that constrain the nature of dark energy, test General Relativity, measure the mass of the neutrino, and gain insight on the mechanism by which the initial seeds of structure formation were generated. I accomplish this by focusing on the optimization of analysis methods, the identification and amelioration of spurious trends in the data, and the assessment the proper statistical significances of and correlations between measurements derived from the data.
I also work on instrumentation for the Dark Energy Spectroscopic Instrument (DESI). Specifically, I am working on the “Commissioning Instrument“, which will optimize the telescope performance ahead of the DESI program.
