Project Talks

If you are invited to give a presentation, whether a project short talk  or long talk, you will receive an individual message with details from the meeting organizers. You can find additional details (e.g., submission deadlines, links to the list of PIs who are required to give a talk, presentation templates, etc.) at:

Poster Sessions

A total of six poster sessions (two per day) are programmed over the three-day meeting. All PIs of active NRI and FRR projects, including those in NCE, should prepare one poster per project whether it be a collaborative or independent. Each poster will be assigned to one poster session, meaning that, if a PI has more than one award, each will require a separate poster. 

Posters should explain research by all collaborators and note all award numbers, institutions, and names of PIs/Co-Ps. The lead PI or alternate(s) for each project is responsible for submission of electronic copies via the "Submit Poster" tab or at no later than 11:59 pm on Wednesday, March 30, 2022. 

Posters will be uploaded into by the meeting organizers. The electronic versions will be posted to the website. The electronic copy must be submitted in PDF file format.

Templates for preparing posters can be found at:

All poster sessions will take place within the platform. Within Gather, presenters will navigate to their virtual poster booth and present to those attendees who visit their booth.
