The main organized path for undergraduate research in economics is the senior honors thesis.
Aside from the honors thesis, students need to approach faculty members directly and inquire whether they can work on one of the faculty members’ projects. This works best if the faculty member already knows the student.
For help with this process, please contact the undergraduate research liasion; currently this is myself (Lutz Hendricks).
These are announced in late fall, with applications due in March.
An additional option is the University work-study program.
