In that function, I an editing and publishing the monthly WMF reports, introduced the separate, translation-friendly Wikimedia Highlights format, worked on the WMF annual reports, co-founded and co-edit the Wikimedia Research Newsletter, and form part of the groups that take care of https://blog.wikimedia.org/ and the official social media accounts for Wikipedia and other.
