Ruth Charney

Ruth Charney holds the Theodore and Evelyn Berenson Professorship in Mathematics at Brandeis University. Her research specializes in geometric group theory, particularly CAT(0) spaces, hyperbolic groups, Artin groups, and automorphism groups. She earned her Ph.D. from Princeton University (1977) after undergraduate studies at Brandeis. She previously held positions at Ohio State University, Yale University, and UC Berkeley.

Her foundational work explores geometric structures of groups, boundaries of metric spaces, and random group properties. Recent publications focus on outer space constructions for Artin groups, Morse boundary classifications, and acylindrical hyperbolicity in infinite-type groups.

Honors include presidencies of the American Mathematical Society (2021-2023) and Association for Women in Mathematics (2013-2015), Polya Lectureship, and multiple fellowships. She has supervised 17 Ph.D. students and secured continuous NSF funding since 2011 for projects on automorphism groups and geometric structures.

She organized major conferences including Artin groups workshops at MSRI and Oberwolfach, and serves on advisory boards for CRM Montreal, MSRI, and multiple NSF panels. Her outreach includes lectures at international conferences and programs advancing women in mathematics.
