This is the website for an algebraic topology conference series meeting every two years in San Juan, Puerto Rico supported by the National Science Foundation, Purdue University, the Institute of the Mathematical Sciences of the Americas at the University of Miami, and the University of Puerto Rico. The conferences will feature a variety of events focusing on recent developments in algebraic topology and their applications to geometry, physics, and data science.

The next iteration of the series will occur on June 5 - June 14, 2024. This event will have three parts. From June 5th to June 7th it will feature three introductory mini-courses on the topics of configuration spaces, algebraic K-theory, and string topology accessible to graduate students and researchers in related fields outside algebraic topology. The lecturers will be Ben Knudsen (Northeastern University), Teena Gerhardt (Michigan State University), and Florian Naef (Trinity College Dublin), respectively. On June 8th, there will be a special event directed towards the general public featuring talks by Alejandro Adem (President of Natural Sciences and Engineering Research Council of Canada, University of British Columbia) and Robert Ghrist (UPenn). Both of these events will take place at the University of Puerto Rico - Rio Piedras campus. The main research conference will then take place from June 10th to June 14th at the AC Hotel Condado in San Juan. It will feature talks by invited speakers as well as contributed talks. More information will be available soon.

Registration for the 2024 conference will close on March 15, 2024.
