Research Experiences for Undergraduates (REU)

The Research Experiences for Undergraduates (REU) program is funded by the National Science Foundation (NSF) and supports active research participation by undergraduate students in astronomical research.  REU projects involve students in meaningful ways in ongoing research programs or in research projects specifically designed for the REU program. Students may not apply to NSF to participate. Students apply directly to the REU Site.

Pathways to Science

Pathways to Science is a project of the Institute for Broadening Participation (IBP). It supports pathways to the STEM fields: science, technology, engineering, and mathematics. Pathways to Science places particular emphasis on connecting underrepresented groups with STEM programs, funding, mentoring, and resources. Its website can be used to find undergraduate summer research opportunities, graduate fellowships, and postdoctoral positions.
