Interactive Events

We organize several interactive activities that constitute a platform for researchers to increase their visibility in the field, and to get to know the community, all that in an informal atmosphere. These activities are targeted at young researchers, but everybody is welcome to attend!

Upcoming activities

AA"Tea"RN Tea-time

During the tea-time you have the possibility to meet new scientists in an informal atmosphere! In groups of about four,  folks are welcome to chat about whatever they like!

The next tea-time will take place on Wednesday, July 3, 2024, at 11am Eastern Time.

Tutorial-a-thon 2024

The next tutorial-a-thon is planned for 2024. Stay tuned! For more details, check out our Tutorial-a-thon webpage.

Poster Sessions

We are organizing open poster sessions via Gather.Town, with the intention of giving a platform to younger members of our community to showcase their work, as well as a place for everyone to present their most recent research results. Topics of interest span the full range of applied and computational topology. The date of the next poster session is not decided yet.
