Suzan Edwards (b. 1951) is the L. Clark Seelye Professor of Astronomy at Smith College. Edwards studies and has made significant contributions to the understanding of the formation of stars, the evolution of planet-forming disks, and the role played by disk- and stellar-driven winds during the early phases of stellar evolution.
