Sun-Yung Alice Chang

Sun-Yung Alice Chang is a distinguished mathematician holding the Eugene Higgins Professorship in the Department of Mathematics at Princeton University. She has been a faculty member since 1998 and served as department chair from 2009 to 2012. Her research focuses on geometric nonlinear partial differential equations, conformal geometry, and isospectral geometry, with notable contributions to Sobolev inequalities, Q-curvature, and the Yamabe problem.

Chang earned her B.S. from National Taiwan University (1970) and her Ph.D. from the University of California, Berkeley (1974). She held academic positions at SUNY Buffalo, UCLA, and the University of Maryland before joining Princeton.

Her work has been recognized with prestigious awards, including the Ruth Lyttle Satter Prize (1995) and a Sloan Fellowship (1979–1980). She has served on committees for the National Academy of Sciences and the National Science Foundation, and her research often intersects with extremal metrics, geometric flows, and spectral geometry.
