Barbara Sue Ryden (born May 2, 1961) is an American astrophysicist who is a Professor of Astronomy at Ohio State University. Her research considers the formation, shape and structure of galaxies. She was elected a fellow of the American Association for the Advancement of Science in 2016.

Early life and education

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

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]

Awards and honors

• 1994 National Science Foundation National Young Investigators Award ^[12]
• 2006 American Astronomical Society Chambliss Astronomical Writing Award for her book Introduction to cosmology ^{[13] [14]}
• 2016 Elected Fellow of the American Association for the Advancement of Science ^[15]
