Math Peer Mentor Program

The math department has established an informal peer mentoring system, where junior and senior mathematics majors provide advice and information about the major. They can answer questions about what it’s like to major in mathematics, about our classes, job and research opportunities, summer programs, and so on.  Our peer mentors are friendly and always happy to help!  If you have any questions about the math major or math at Yale more broadly, you’re very welcome to find out more and sign up for a mentor here.


Summer Undergraduate Research at Yale (SUMRY)

The SUMRY program is a ten-­week undergraduate research program run by the mathematics department at Yale University, usually between early June and early August. In a recent year, there were 15-20 funded positions for undergraduates to investigate open research problems in the mathematical sciences. Students work either individually or in small groups, directed by faculty members, post­doctoral fellows, and graduate students. The work pursued in this program will give participants an idea of what research in mathematics is like.

Yale Undergraduate Math Society (YUMS)

The Yale Undergraduate Mathematics Society, or YUMS, aims to create and foster a community for undergraduates at Yale interested in mathematics. It does so by hosting a number of events for math students, including colloquia, study sessions, game nights, and panels about the math major and summer opportunities.   Up to date sign-up and contact information here.


Dimensions is an association for women and gender minorities in math at Yale. Their objectives are: To create a network and community that celebrates the accomplishments of women and gender minorities in math at Yale; to indicate a presence of women and gender minorities in the math department and be a resource for prospective mathematics students; to provide avenues for support and mentorship of current students and faculty; to help connect undergraduates, graduate students, postdocs and faculty. Dimensions is a student-led organization, which is Yale’s chapter of the AWM, and the group aims to inspire, celebrate, and empower women and gendered minorities in mathematics.  Up to date sign-up and contact information here.


Yale MathCounts Outreach is an Undergraduate Organization working to provide after-school math enrichment programs for New Haven Middle and Elementary School students and to help younger students stay engaged with math. Yale students teach math curriculum weekly in most New Haven public middle schools, as well as some New Haven elementary schools.  MathCounts Outreach organizes and executes numerous large-scale events throughout the year. Girls’ Math Day is one of these events, held annually in the fall to celebrate the accomplishments of women in math, and to encourage our female students to continue their studies. There are also two New Haven-wide math competitions during the spring semester, including the annual February Competition and April Competition that brings students from all over New Haven to compete and learn in a friendly, rewarding, and intellectually stimulating environment.  Up to date sign-up and contact information here.

DSAC - Applied Math

The Applied Math DSAC (Departmental Student Advisory Committee) was formed in Spring 2019 to consolidate input and feedback from students to help the Director of Undergraduate Studies make continuous improvements to the major, develop resources for undergraduates in the major, and to assist the DUS with the maintenance of the Applied Math website.  (Note, this is separate from the Student Advisory Committee for the math department)


The BATMOBYLE is a vehicle for bringing together the algebraic and tropical geometry groups of Brown and Yale for a biannual day of talks alternating between the two universities.


MMATHS is an undergraduate organization dedicated to fostering enthusiasm for mathematics among high-school students by hosting a math competition.  We also assist math majors at other universities in hosting their own competitions and promote connections between undergraduate math students across the country.   We are a fun and inclusive organization that enjoys working together!  From logistical planning to problem-writing to day-of volunteering at competitions, we welcome the support of anyone.  For more info about getting involved, please contact or
