Hi. I'm Aaron Halfaker. I've been a Wikipedian since 2008. I'm half computer scientist, half social scientist. See my publications. In 2011, I started working with the Wikimedia Foundation as a researcher. See my volunteer account, en:User:EpochFail, for my non-staff work.
My workI use the scientific method to explore the underlying patterns of wiki-work, to discover problems and to design new tools for readers, editors and community organizers. See The Rise and Decline for an example of my research and Snuggle for an example of a tool for Wikipedians that I'm actively developing.
Disclaimer: Although I work for the Wikimedia Foundation, contributions under this account do not necessarily represent the actions or views of the Foundation unless expressly stated otherwise. For example, edits to articles or uploads of other media are done in my individual, personal capacity unless otherwise stated.
