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.
