Anybody can become a Math DUG officer, including those students who are not concentrating in math or not taking math classes. If you're interested in joining the DUG, you can show up at our weekly tea/cookies (Fridays in Kassar) or contact an officer.
The DUG maintains an active listserv, where we post announcements of DUG events, math-related research and employment opportunities, and much more.
You can sign up to receive DUG emails on the Brown Listserv Website. Alternatively, you can contact the DUG officers if you would like to be added to or removed from the listserv.
