Each year NCUR® sponsors an annual conference where more than 1,600 undergraduates from over 400 colleges and universities present their research in at least fifty-six academic disciplines. Four fields have historically represented more than half of those presentations-biology, chemistry, psychology, and physics. The term "research experience for undergraduates (REU)," now a standard phrase in the vocabulary of undergraduate research, came to us, too, from the National Science Foundation and programs in the sciences.
