| about me = Hi. I'm [[:en:Aaron Halfaker|Aaron Halfaker]].  I'm a scientist.  See [[#Projects|projects]] and [[#Publications|publications]] below.  I've been a Wikipedian since 2008.   I mostly build tools and run studies, but I make edits where I can.  In 2011, I started working with the Wikimedia Foundation as a [[:en:Scientist|research scientist]].  This is my staff account.  See my volunteer account, [[User:EpochFail]], for my non-staff work.  

| about my work = My job is to build understanding about and support for the socio-technical fabric of the Wikimedia movement.  I tend to focus on our computer mediated spaces (Wikipedia, Commons, Wikidata, Wikisource, etc.) and quality dynamics (patrolling, curation, newcomer training, etc.)

See [[:m:Research:The Rise and Decline|The Rise and Decline]] for an example of my research and [[:m:Research:Revision scoring as a service|Revision scoring as a service]] for an example of an experimental technology I'm actively working on.
