Ashley Ross

Ashley Ross is a Research Assistant Professor at The Ohio State University, affiliated with the Department of Astronomy. His research focuses on cosmology and large-scale structure, particularly leveraging data from projects like DESI (Dark Energy Spectroscopic Instrument) and the Roman Space Telescope Galaxy Redshift Survey. He specializes in optimizing data analyses, interpreting large-scale structure surveys, and assessing cosmological constraints related to dark energy, general relativity, and neutrino mass.

Education: B.A. in Physics from Carleton College (2004), Ph.D. in Astronomy from the University of Illinois (2009). Postdoctoral positions include roles at Portsmouth University (2009–2014) and Ohio State University (2014–present).

Research interests include cosmological parameter estimation, galaxy clustering, baryon acoustic oscillations (BAO), and the optimization of observational techniques. Ross has contributed to DESI's data releases, commissioning instruments, and cross-correlation analyses between galaxy surveys and CMB lensing.

Key contributions include analyses of DESI DR1 and DR2 data, studies of galaxy-galaxy lensing, and validation of BAO measurements. His work addresses systematics mitigation and robust statistical methods in cosmology.
