TGIF Program Associates

The TGIF Program Associates internship program first began in February 2013. The TGIF Program Associates assist the TGIF Coordinator with the documentation of TGIF-funded projects. Duties include recording and calculating both quantitative and qualitative sustainability metrics produced by these projects and involve reading project updates, reports, and interviewing project leaders. The TGIF Program Associates also assist TGIF’s Coordinator with displaying and publicizing these metrics through new and innovative ways, including blog posts, articles, videos, and social media.

She grew up in the under-rated city of Pittsburgh, Pennsylvania. Go Steelers!

The Green Initiative Fund (TGIF) provides funding for projects that reduce UC Berkeley’s negative impact on the environment and make UC Berkeley more sustainable. TGIF will allocate funds to projects that promote sustainable modes of transportation, increase energy and water efficiency, restore habitat, promote environmental and food justice, and reduce the amount of waste created by UC Berkeley. Portions of the fund also support education and behavior change initiatives, student aid (via return to aid), and internships. TGIF is supported by student fees and administered through a student-majority committee and a program coordinator.
