Summer REU Program

A Cayley graph embedded on a torus, which has been the subject of Research Experience for Undergraduates work at Lafayette College.

Lafayette’s Research Experience for Undergraduates (REU) Program is an intensive, eight-week summer research experience in which undergraduate students investigate unsolved problems in mathematics. It is sponsored by the National Science Foundation and Lafayette’s Excel Scholars program. Over the past n years, more than 8n students have participated in the program (where the value of n increases every year, usually by 1), working in small groups directed by individual faculty members.

Most students who have participated in the Lafayette program have published papers in professional journals and presented talks on their summer research at national mathematics conferences. The picture above, taken from a student presentation, shows a Cayley graph embedded on a torus. In the photo below, Betsy Cassells presents her work on PSL(2,Z[i]) at the national American Mathematical Society-Mathematical Association of America meeting in San Antonio.

We will not be running an REU during the 2015 summer. However, we have applied to the NSF for funding to continue the program in the summer of 2016 and beyond. Please check this page for updates.

The REU is coordinated by the Mathematics Department of Lafayette College, which is located in Easton, Pennsylvania, less than 90 minutes from both New York and Philadelphia. Participants receive free housing and a stipend. Participants are expected to continue their undergraduate education after the summer is over, and NSF regulations require that only U.S. citizens and permanent residents are eligible to receive stipends.

Arthur D. Gorman

With deep regret and a profound sense of loss we sadly announce the death of our esteemed colleague and dear friend, Arthur D. Gorman, Associate Professor of Mathematics. Professor Gorman died on December 15, here in Easton. He is survived by his two daughters--Anne Gorman of Seattle, Washington and Mary Gorman of State College, Pennsylvania--and by his brother Mark Gorman of Littleton, Colorado.
