BioGeoMon 2026 is proud to welcome a distinguished group of plenary speakers who are internationally recognized for their contributions to biogeochemistry, ecosystem science, and environmental change. These leaders will open each day of the conference with inspiring talks that reflect the breadth and urgency of our field—from critical zone processes and climate extremes to interdisciplinary frontiers.

Our plenary sessions are designed to set the stage for in-depth discussions, highlight emerging research, and foster connections across disciplines. Join us in Umeå to hear their perspectives and help shape the future of biogeochemical research.

A full list of plenary speakers will be announced soon.
