The 9th International Conference on Applied Category Theory will take place
at the Estonian Maritime Academy of Tallinn University of Technology,
Tallinn, Estonia from 6 - 10 July. The conference will be preceded by the
Adjoint School Research Week from June 29 - July 3, 2026. This conference
follows previous events at Florida (2025), Oxford (2024), Maryland (2023),
Strathclyde (2022), Cambridge (2021), MIT (2020), Oxford (2019) and Leiden
(2018).


Applied category theory is important to a growing community of researchers
who study computer science, logic, engineering, physics, biology,
chemistry, social science, systems, linguistics and other subjects using
category-theoretic tools.  The background and experience of the community
is as varied as the systems being studied. The goal of the Applied Category
Theory conference series is to bring researchers together, strengthen the
applied category theory community, disseminate the latest results, and
facilitate further development of the field.

*SUBMISSIONS*

1. Research
