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.
