Undergraduate and Faculty Research Outcomes

A high proportion of faculty from each REUF workshop go on to mentor undergraduate researchers, and many faculty also continue collaborating with fellow faculty workshop participants and mathematical leaders. Outcomes are tracked for two years after each workshop, starting a year after the workshop.

Faculty participants: 235 faculty from more than 100 primarily undergraduate institutions have participated in a REUF workshop since 2008.

Student research: 390 undergraduate students were mentored by REUF alumni in research. Collectively, the students made 277 presentations, completed 22 honors theses, and co-authored 9 publications. Thirty-four student-faculty collaborations received other grant funding. Several students were accepted to off-site NSF REU programs, and one won first prize for a presentation at a national meeting.

Faculty research: Ninety-one undergraduate faculty were involved in new collaborations with other faculty. More than 20 small research groups met for an additional week with support from the REUF program. All together, their research has resulted in 77 presentations and 51 research articles in various stages of publication, some with student co-authors.

Other notable outcomes:

• Special sessions at the Joint Mathematics Meetings organized by REUF alumni
• Development of new undergraduate courses on REUF research topics
• Departmental changes such as the creation of a for-credit undergraduate research seminar for math majors
