Applied Algebraic Topology Research Network

Bringing together researchers across the world to develop and use applied and computational topology.

Find out how you can participate and join AATRN (membership is free and so are all events), or check out all our content on our YouTube channel. We invite you to join the following activities, which we are currently organizing:

We have a weekly Seminar Series (or sometimes a tea time) on Wednesdays.

August 18-22, 2025. This week-long conference is in celebration of the 10-year anniversary of AATRN. AATRN will be “geometrically realized” in-person at the Institute for Mathematical and Statistical Innovation in Chicago, USA!

The Networks seminar covers applications and theory of how network structure is revealed through topology and algebra.

Co-organizers: Daniela Egas Santander, Jānis Lazovskis,  Henri Riihimäki, and Jason Smith

This seminar, organized by Dan Cohen, Jesus Gonzalez, and John Oprea, focuses on topological complexity and related topics.

See our upcoming interviews.

Our next tutorial-a-thon is in 2024. Stay tuned!

Our most recent poster session was on November 10, 2023, jointly organized with CIMAT (Centro de Investigación en Matemáticas, Guanajuato), as part of the 9th Mexican Workshop on Applied Geometry and Topology!

Stay tuned for our next poster session!

The Vietoris-Rips seminar considers connections between applied topology, quantitative topology, geometric group theory, topological combinatorics, etc.

This seminar ran 2021-2023, but is currently paused.
