We're excited to hear from Abby André and Jonathan Gilmour from the Impact Project as Joint Keynote speakers!

Thanks to the many people who have already submitted abstracts, and thanks to those of you who have accepted the review invitation through Easy Chair!

It's a priority that we limit the volume of review to a reasonable number to avoid review burnout (ideally five abstracts per person), but to do so we need a robust community of reviewers participating.

Abstract submissions close on March 3rd!

We are also extending a ✨ call for mentored reviewers ✨ if you advise excellent graduate or postdoctoral researchers you are welcome to recommend them to review for IC2S2 2026. Email IC2S2@uvm.edu to nominate mentored reviewers (or faculty colleagues)
