Astrophysicist specializing in galaxy formation, the circumgalactic/intergalactic medium, and quasar absorption lines. My work combines large-scale surveys (DESI, SDSS) with data science and computational methods to understand cosmic gas flows and the metal cycle in the Universe at different epochs. My long-term vision is to build an independent research program at the intersection of large surveys, data-intensive pipelines, and galaxy–CGM/IGM connections.
