Interactive Events

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, June 24, 2026, at 11am Eastern Time.

We have organized open Tutorial-a-thons via Zoom, with the intention of creating community-serving tutorial videos on applied topology. For more details, check out our Tutorial-a-thon webpage.

We have organized 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.

We hosted four tea times in 2025, four in 2024, four in 2023, five in 2022, five in 2021, and two in 2020.

We co-organized AATRN’s first-ever in-person conference, The Geometric Realization of AATRN. It was held at iMSi, the Institute for Mathematical and Statistical Innovation, in Chicago, IL, USA, over August 18-22, 2025. Here is the conference website: imsi.topology.rocks

We intentionally did not pack the schedule with too many talks. We encouraged folks to sign up to present posters, and in fact hosted two poster sessions to accommodate all interested attendees. We met the building capacity of the iMSi institute, which to the best of our understanding was a new occurance! Talks were also live-streamed, recorded, and will be posted on AATRN’s YouTube channel.

Our most recent Tutorial-a-thon was in Spring, 2025. For more details, check out our Tutorial-a-thon webpage.

We organized our fourth poster session via Gather.Town, jointly with CIMAT (Centro de Investigación en Matemáticas, Guanajuato) as part of the 9th Mexican Workshop on Applied Geometry and Topology, on November 10, 2023, at 11:00am Central Time (UTC-6) = 18:00 Central European Time (UTC+1)! We had 11 poster presenters and many attendees.

We organized our third poster session via Gather.Town, joint with APATG, on September 20, 2022, at 9:00 Central European Summer Time (UTC+2) = 16:00 Japan Standard Time (UTC+9)! We had 20 poster presenters (split into two blocks of ten), and 46 attendees.

Our second Tutorial-a-thon took place on October 28, 2021, with follow-up meetings on November 4 and November 11. 

The recordings can be found here.

Our first poster session took place on October 8th, 2021, with 26 amazing posters, and over 50 attendees! You can check out the posters here:

March 2021 saw the first Tutorial-a-thon, developed in conjunction with WinCompTop and organized by Henry Adams, Hana Dal Poz Kouřimská, Teresa Heiss, Sarah Percival, and Lori Ziegelmeier. 

Members of the AATRN community produced a great variety of tutorial-level video content, ranging from theoretical principles to running code and data applications.

The recordings can be found here.

We have written an article on How to Tutorial-a-thon in the October issue of the AMS notices.
