JMM is the largest annual mathematics meeting in the world, and offers a variety of sessions that are designed to appeal to undergraduates. One such annual event is the undergraduate poster session. This session is reserved for undergraduate and first-year graduate students submitting posters on work done while an undergraduate. Posters will be judged during the session and award certificates will be mailed to presenters with the highest scores. There are over 200 professional mathematicians participating on the judging panel, so this is a great opportunity to get your work noticed by leaders in your field.
