Early life and education

edit

Ryden studied physics and integrated sciences at Northwestern University.[1] She moved to Princeton University as a doctoral student, where she worked alongside James Gunn.[2] She was a postdoctoral research fellow at the Center for Astrophysics | Harvard & Smithsonian[3] and Canadian Institute for Theoretical Astrophysics.[4]

Research and career

edit

Ryden joined the faculty at Ohio State University in 1992. She studies the formation and shapes of galaxies.[5][6] Her research made use of the Sloan Digital Sky Survey and various numerical simulations.[7] She has shown that the galactic disks at the centre of spiral galaxies are more elliptical than circular.[8]

Ryden has written several astronomy textbooks, including Introduction to Cosmology,[9] Interstellar and Intergalactic Medium,[10] and Foundations of Astrophysics.[11]
