Mathematics and Statistics Student Seminars

The Mathematics and Statistics Student Seminar series is a forum for undergraduates to present talks on topics of general interest in mathematics and statistics. Its meetings, usually on Wednesdays or Thursdays at 4:15 p.m., are open to everyone in the Grinnell College community.

By long tradition, each meeting begins with fifteen minutes of informal conversation in the department lounge (Science 2400), over refreshments, followed by a migration into one of the nearby classrooms for a talk of forty to sixty minutes, including questions from the audience.

The faculty sponsor and organizer of the Mathematics and Statistics Student Seminar series is Professor Keri Kornelson. If you're interested in giving a talk, send e-mail to Professor Kornelson or drop in at her office (Science 2401).
