UF DSI is a student organization that spans multiple disciplines and colleges at the University of Florida. They have a website and a Facebook group. They have a large, active board and are devoted to helping students advance their skills.
To that end, they offer free workshops throughout the academic year. Workshops cover Python, R, SQL, and data visualization. Links to DSI GitHub repos for each workshop series can be found on the website, and dates and times for workshops come through the Facebook group.
