Do you know of anyone at UCLA using Drupal right now?
Yes. Me amongst others.
Drupal currently supports the Semel Institute www.semel.ucla.edu, and uses Organic Groups to host 60+ center and program sites; the UCLA Family Commons (www.uclacommons.com) was developed in-house by Center for Community Health
School of Public Affairs www.publicaffairs.ucla.edu used an external developer to implement their current site.
