I am a biophysicist (Q14906342) working for the University of Virginia (Q213439) and interested in integrating research (Q42240) workflows with the Internet (Q75) — particularly if they relate to medicine (Q11190), Biodiversity (Q47041) or open science (Q309823). My contributions here cover similar topics, with a focus on scholarly publications as sources for statements in Wikidata. I enjoy most of the interactions with the Wikidata community, which sometimes trigger wiki thanks.

For semi-automated or tool-assisted edits, I am experimenting with a separate account over at User:Research Bot.

Topic Pages[edit]

The PLoS Computational Biology articles serving as the basis for Wikipedia entries should be properly represented at Wikidata, which they are not yet. Dumping the list here for the moment - help is welcome.

These should link to the respective topic items via "main subject".

Babel user information[edit]

I find the current way of handling this information rather unwieldy, but since it is basically required for editing Wikidata in multiple languages, I'm just pushing it to the bottom of the page, along with some pointers to topics or tools of interest.
