**MAA Student Poster Session, **organized by **Chasen Smith**, Georgia Southern University, and **Eric Ruggieri**, College of the Holy Cross; January 6-9, 2021. This session features research done by undergraduate students. First-year graduate students are eligible to present if their research was completed while they were still undergraduates. Research by high school students can be accepted if the research was conducted under the supervision of a faculty member at a post-secondary institution.

Appropriate content for a poster includes, but is not limited to, a new result, a new proof of a known result, a new mathematical model, an innovative solution to a Putnam problem, or a method of solution to an applied problem. Purely expository material is not appropriate for this session.

Participants should submit an abstract describing their research in 250 words or less by midnight, **Friday, November 6, 2020**. Notification of acceptance or rejection will be sent in late November. See www.maa.org/programs/students/undergraduate-research/jmm-student-poster-session for further information on what should be included in the abstract ,a link to the abstract submission form, and for any other changes.

Posters will be judged during the session and feedback from these judges will be available at the conclusion of the conference. The sessions will also be open to all registered participants of the meeting, so that friends, colleagues, and advisors can view your work. Questions regarding this session should be directed to **Eric Ruggieri** at eruggier@holycross.edu and **Chasen Smith** at csmith@georgiasouthern.edu. This session is sponsored by the MAA Committee on Undergraduate Students (CUS).
