Stephanie Tonnesen, Ph.D.

Associate Research Scientist, CCA, Flatiron Institute

Stephanie Tonnesen joined the foundation in 2017 as an associate research scientist at the Center for Computational Astrophysics. Her research interests lie in the fields of galaxy formation and evolution. A focus of her research is examining how a galaxy’s environment can impact its growth. To study how galaxies evolve, Tonnesen uses both cosmological simulations spanning large regions of the ‘universe’ and smaller, galaxy-scale simulations. She completed her Ph.D. at Columbia University. Before joining the foundation, Tonnesen was a Lyman Spitzer, Jr. Postdoctoral Fellow at Princeton University and an Alvin E. Nashman Fellow at the Observatories of the Carnegie Institution for Science.
