I am a biophysicist (Q14906342) interested in integrating research workflow (Q115682347) with online collaboration (Q116095133) — particularly if they relate to biodiversity (Q47041), medicine (Q11190), mathematics (Q395), cultural heritage (Q210272) or open science (Q309823). My contributions here cover similar topics, with a focus on scholarly publications as sources for statements in Wikidata, and the integration of scholarly and Wikimedia workflows more generally.

My most recent affiliations are as follows (see my ORCID profile for details):

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.
