2022 Fellows' Poster Session & Abstracts

Fellows present their research at the annual poster session.Wednesday, June 22 — 5:00-6:30 p.m.

Anasazi North

The annual Fellows’ Poster Session afforded attendees a unique opportunity to learn more about the research supported by the DOE NNSA SSGF and DOE NNSA LRGF programs. The session was divided into two groups, and each presenting fellow was provided space to highlight their latest findings. This format allowed all attendees – including fellow presenters – to ask questions of and engage in discussion with one another.

Group I — Presenting 5:00-5:45 p.m.
