Founder of the Open Knowledge Association, supporting full-time Wikipedia translation work.

AI

This user supports human-reviewed use of LLM tools on Wikipedia.

This user feels that deletions subject to a popularity contest rather than a verifiability test damage Wikipedia more than any userbox ever could.

This user comes from Switzerland.

This user is an effective altruist.

I am the main founder and president of the Open Knowledge Association (OKA), a non-profit providing grants to full-time Wikipedia translators. The articles we created are listed here. The work I do on Wikipedia and for OKA is during my free-time only, without any link to my full-time activity or to my employer.

My philosophy for life is Effective altruism. I fix what I find when browsing Wikipedia and try to contribute on pages where I feel that it would maximize my Social return on investment. In particular, I tend to focus on the fields of statistics, game theory, computer science, economics, and Switzerland. I spend most of my time on the lead section of articles, on simplifying definitions and clarifying the differences between similar terms and topics.

Personal contributions

I keep here a list of my main Wikipedia contributions (outside of the work on OKA), mostly to keep a personal history but also for transparency. Note that I am not an expert on any of those topics, but that I only make changes when I have reached a high level of confidence in the accuracy of what I wrote.
