Welcome to CIROS

Who We Are

CIROS was founded in March 2018 as a student initiative aimed at fostering social cohesion within the IRO student community through a range of academic and non-academic events.

Since then, we have grown to become a registered Student Association within Leiden University, with 10 committees, several clubs, as well as several ongoing projects. We are composed of students from over 25 different nationalities.

Our mission is to build a community that every IRO student can feel a part of.

Become one of our new Committee Heads!
