ProfileRuth Charney is a Professor of Mathematics. Her expertise is in the fields of Geometric Group Theory and Topology. In geometric group theory, one studies groups of symmetries of geometric objects, using the geometry to better understand the algebraic structures of these groups. Charney's work focuses on the geometry of metric spaces of non-positive curvature and their symmetry groups. She enjoys giving public lectures that give insight into the beauty of abstract mathematics to the general public. In addition, she is involved in various activities designed to encourage and support women in mathematics, both on campus and nationally. She has recently complete a term as President of the Association for Women in Mathematics and is currently Chair of the Board of Trustees of the American Mathematical Society. Webpage
