Help close the gender gap on Wikipedia this International Women's Day

What we’ll do

Spend an afternoon editing Wikipedia pages about women and gender-diverse people in STEM.

No experience needed. Just curiosity.

Why this matters

In Wikipedia, right now, only about one in five biographies are about women. In STEM, the gap is even wider, especially for gender-diverse people. If it’s missing from Wikipedia, it’s probably missing from how science is remembered, cited and increasingly trained into AI systems.

So let’s fix some of this, together!

What’s in it for you

• Learn how Wikipedia actually works, by the Wiki NL team
• Do something concrete with real impact
• Meet interesting people from the Leiden life-sciences community
• Leave knowing you changed something that matters

Free entry. Bring your laptop and we’ll take care of the rest.

This event is organized by Talent-CGT , TOPX Network, Leiden Bio Science Park (the biggest LSH cluster in NL) and BioPartner.
