Math Circles are fantastic programs for students enthusiastic about math, as well as for getting students enthusiastic about math. As a graduate student I often held sessions at the Berkeley Math Circle, and currently I hold sessions at the Math Circles of Chicago. If you live in North America, click here to find a math circle near you.
Outliers: I love playing football (soccer) and it is always great fun to play with the Berkeley Statistics co-ed team. Despite our name, our results are often dead average (more than once we finished our season with a W3-D1-L3 record).
In May 2015 we participated in a fundraising tournament with all benefits going to Soccer Without Borders Oakland. Soccer Without Borders has a great mission, using soccer as a vehicle for positive change, working with many schools that serve immigrant and refugee youth.
The tournament was a success both on and off the pitch---check out our fundraising page (and if you can, consider contributing to a worthy cause). Finally living up to our name!
