XXTH ANNUAL SIGMA XI Early-Career POSTER PRESENTATION

AbSTRACT DUE DATE: Friday, March 24th, 2023

Poster PDF & Recordings due date: Wednesday, March 9, 2022

PRESENTATION DATE: Wednesday, March 30, 2022

AWARDS CEREMONY TO FOLLOW

The NIST chapter of Sigma Xi invites all early-career staff and associates to produce a prerecorded poster presentation on their scientific or technical research and participate in a live question & answer session with their NIST colleagues, collaborators, and friends. All NIST researchers who have received their terminal academic degree in the last five years are welcome to participate. Those new to NIST may present research from their previous institution. The attendees are also invited to the virtual awards reception where the most outstanding posters will be announced.

Poster Submission Categories:

• Physics

• Materials

• Chemistry

• Biological Sciences (including Biology, Biochemistry, and Biotechnology)

• Mathematical Sciences (including Mathematics, Statistics, and Data Science)

• Computer Sciences (including Artificial Intelligence, Machine Learning, and Software Programming)

• Cybersecurity and Network Communication Technology

• Engineering and Manufacturing

Benefits of Participation

NIST Sigma Xi’s annual poster event (formerly the Postdoctoral Poster Presentation) is one of the few NIST-wide research forums available to showcase your work. This represents an excellent opportunity to make connections in other parts of NIST and across NIST OUs to advance your research and forge new collaborations. In addition, this is a great resume-building opportunity and a unique way to showcase your results!

ABSTRACT SUBMISSION HAS CLOSED

If you would like to support our early-career researchers through this event, consider joining the Sigma Xi Early-Career Poster Presentation Organizing Committee or volunteering to be a poster judge and/or session chair. If interested, please contact Organizing Committee Chair Adam Biacchi. For more general questions, contact the Chapter Executive Committee.
