Melanie Stein is Dean of Academic Affairs and Professor of Mathematics. She graduated with an A.B. in Mathematics from Harvard College in 1983, and she received the Ph.D. in Mathematics from Cornell University in 1991. She taught for three years at the Ohio State University and spent one year on a NATO-NSF fellowship at the Johann Wolfgang Goethe Universitat in Frankfurt, Germany before coming to Trinity in 1995.

Professor Stein's research is principally in geometric group theory, a field straddling the border of algebra and topology. The main goal of her research is to investigate the algebraic properties of infinite groups by studying the geometric properties of the groups themselves and other topological spaces on which they act.

Professor Stein’s goal in teaching is to help her students learn to think clearly and logically and to enable them to experience the beauty of mathematics. The small class size setting at Trinity complements her teaching style; she especially enjoys working with students one-on-one.
