Observational Cosmology

My research involves the analysis of modeling and observational systematics understood to impact measurements of the galaxy clustering signal from wide-field spectroscopic surveys to address potential biases in the constraints of cosmological parameters. Surveys such as the Sloan Digital Sky Survey (SDSS; Alam et al. 2021), Dark Energy Spectroscopic Instrument (DESI Collaboration et al. 2016), ESA’s Euclid mission (Laureijs et al. 2011), the Subaru Prime Focus Spectrograph (PFS; Takada et al. 2014), and NASA’s Nancy Grace Roman Space Telescope (Wang et al. 2022), have collected (or will collect) the light from millions of galaxies to map out the distribution of matter in the Universe and attempt to uncover the nature of dark matter and dark energy. Employing mock galaxy catalogs from simulated universes, forecasts of galaxy statistics such as emission-line luminosity functions and number counts from previous observations and pathfinder studies, simulated instrument data, and collected details for hundreds of thousands of galaxies, I investigate measurements of cosmological signals from the perspective of both theory and observation to identify and mitigate systematic effects.
