Desika Narayanan, Ph.D.
Professor of Astronomy
College of Liberal Arts and Sciences
Desika Narayanan is a leading computational astrophysicist whose work is reshaping our understanding of how the earliest galaxies in the Universe formed and evolved. His research sits at the intersection of large-scale cosmological simulations and cutting-edge artificial intelligence, allowing his group to decode the massive datasets now produced by observatories such as the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array.
“I develop large-scale cosmological simulations to understand the formation of the Universe’s first galaxies,” Narayanan says, “and I pioneer AI tools to decode the flood of data reshaping our picture of cosmic origins.”
Narayanan’s work has been central to advancing the theory of cosmic dust — tiny grains that regulate the physics of star-forming clouds and imprint themselves on nearly every astronomical observation. His group has developed some of the first and most sophisticated models for the formation and evolution of dust in galaxies, a contribution recognized through more than $1.5 million in recent federal funding and his role as a core theorist in 14 international collaborations. His research has produced 224 refereed publications, over 15,800 citations and influential review articles that have become foundational references in the field.
His department chair, Professor Elizabeth Lada, highlights both the depth and impact of his scholarship: “Dr. Narayanan is a widely recognized leader in theoretical studies of galaxy formation and the physics of cosmic dust … His outstanding record of publications, funding, computational innovation, and international leadership makes him exceptionally deserving of a UFRF Professorship.”
Narayanan’s work is also deeply collaborative and global. He is a founding member and international associate of the Cosmic Dawn Center in Copenhagen, a major research hub dedicated to the study of the first galaxies, and he was recently awarded the UK Royal Society Wolfson Fellowship to support research collaborations in Edinburgh. His leadership extends to major NASA and NSF panels, telescope concept teams and international review boards.
Looking ahead, Narayanan is helping shape the future of astrophysics through new AI-driven approaches to simulation-based inference.
