Summer REU

Every summer, Columbia runs a Research Experience for Undergraduates (REU) program. Small groups of undergraduates work with a faculty member instructor and one or two graduate student TAs on a topic related to current research. Some of these REUs are supported by the RTG grant (not all undergraduates in a given REU were supported by the RTG grant; those which were are indicated).
