I'm a Computer Science researcher working on my PhD in the GroupLens Research lab at the University of Minnesota. I moonlight as a Wikimedia Foundation staff researcher. It's a good collaboration.
The majority of my work in English Wikipedia involves the development and maintenance of user scripts that enable communication or otherwise provide insight into the editing process. See my research protocol for more information. I also like to edit articles relating to computer science, mycology, psychology and philosophy.
I use the scientific method to explore the underlying patterns of wiki-work, to discover problems and to invent new tools for readers, editors and community organizers.
- Mr. Clean allows readers to insert cleanup templates in articles.
- Wikignome allows edits to individual sentences while viewing an article.
- NICE is an experimental interface that asks reverting editors to be nice to newbies.
- HAPPI add highlighting to edit pane to visually present information about who last editing wiki-markup and how long ago.
- NOOB adds a visualization of editor experience to talk pages and the revision history page.
- APS Review is a review system for APS:WI to allow members to more easily submit reviews of the articles that they read.
