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.
