About me

Hi. I'm Aaron Halfaker. I'm a scientist. See projects and 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 research scientist. This is my staff account. See my volunteer account, User:EpochFail, for my non-staff work.

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 The Rise and Decline for an example of my research and mw:ORES and mw:JADE for an examples of an experimental technologies I'm actively working on.

Disclaimer: I work for or provide services to the Wikimedia Foundation, and this is the account I try to use for edits or statements I make in that role. However, the Foundation does not vet all my activity, so edits, statements, or other contributions made by this account may not reflect the views of the Foundation.

I've seen you quoted, in more than one news article about Wikipedia 15, discussing the decline in the number of Wikipedia contributors and what can be done about it. --Pine 19:07, 15 January 2016 (UTC)

Hey there. Sherry and I wanted to award you this barnstar for "being awesome". Sorry the rationale isn't much detailed: work logs are also not available :) Rock on, --Elitre (WMF) (talk) 14:25, 27 May 2016 (UTC)
