Macroexpand-Noj - growing the Noj ecosystem

📅 October 17-18, 2025 | Online Conference

The Macroexpand-Noj conference is focused on the growth of the Noj toolkit for data science. Noj is a Clojure toolkit that brings together data processing, visualization, and scientific computing libraries into a cohesive whole. This conference is one of the Macroexpand 2025 pair of conferences organized by Scicloj.

About the Conference

This two-day online event brings together practitioners, library authors, and data enthusiasts to share knowledge, showcase projects, and collaborate on growing Clojure’s data science capabilities. Whether you’re analyzing real-world datasets, building new tools, or documenting existing libraries, this conference is for you.

Call for Proposals

Submission Deadline: September 8, 2025

We invite you to share your work with the Noj ecosystem and broader data science community. All talks must include reproducible code and clear documentation.
