Research Poster Day

The Research Poster Day conference is an annual event featuring cutting-edge science and technology work conducted by our postdocs and their advisors. Postdocs present posters summarizing the exciting research they are involved in the areas of:

Astrophysics and Space Science
Earth Science
Planetary Science and Astrobiology
Technology, Instrumentation, and Engineering

A panel of judges reviews the posters during the event. Top posters are selected from each category, and the winners are announced at the end of the poster session. Winners receive an engraved plaque and briefly summarize their research at an award ceremony held after the poster day event.

Below are links to posters presented by postdocs at the 2025 Research Poster Day.
