David discovered Drupal in 2007 and began working with it full time in 2008. He is an active contributor to Drupal core and various contributed modules, a long-time member of the Drupal security team, and in 2012 became branch maintainer for Drupal 7. Previously he worked at Acquia building Drupal products and services, and at Advomatic building Drupal websites.
David holds degrees in physics and astronomy from Haverford College and Cornell University, and previously worked as a professional astronomer, but a passion for science education and public outreach and a lingering habit of building websites on those topics eventually led him to a Drupal career. He lives in Harrisburg, Pennsylvania with his wife, and enjoys hiking, bird watching, and being outdoors in the Pennsylvania mountains.
