I’m Uendert Andrade, a cosmologist using state-of-the-art galaxy surveys to test the standard cosmological model. My work focuses on large-scale structure, galaxy clustering, baryon acoustic oscillations (BAO), and consistency tests of gravity and dark energy.
I work across observational and theoretical cosmology, with a particular emphasis on turning survey measurements into robust cosmological constraints. Within DESI (Dark Energy Spectroscopic Instrument), I have played leading roles in BAO validation, blinding strategies, and coordination of cosmological results from galaxy and quasar clustering. I am also an active member of DES (Dark Energy Survey), where I am leading the Y6 geometry-growth split analysis.
At UMichigan, I work within the Leinweber Institute for Theoretical Physics and am part of the Huterer Research Group.
Featured Work: DESI BAO
BAO constraints from DESI Data Release 2 are the result of a large collaboration effort. My contributions centered on galaxy and quasar BAO validation, blinding tests, analysis coordination, documentation, plots, and writing, as well as leading the dedicated validation paper.
