PSCR Webinar: Pecha Kucha Portfolios Overview

PSCR 2022 Webinar: Pecha Kucha Portfolios Overview May 18 11:00 a.m. MT

Join the National Institute of Standards and Technology (NIST) Public Safety Communications Research (PSCR)'s Research Portfolio Leads as they provide an overview of the projects housed within their portfolio, and which sessions you can attend at PSCR 2022. Each portfolio overview is delivered in a traditional Pecha Kucha-style presentation, dividing topics into 20 slides that when presented display for only 20 seconds each. The presentations are combined into this 60-minute session to provide viewers with an introduction to all the new and ongoing projects at PSCR and how they are organized within the Mission Critical Voice, Public Safety Analytics, User Interface and User Experience, Location-Based Services, Security, and Resilient Systems portfolios. There will also be time at the end of the webinar for live Q&A from the audience.

This webinar will kickoff PSCR's Annual Stakeholder Meeting: PSCR 2022, which takes place in San Diego June 7-9, 2022. Registration for PSCR 2022 is still open, so register today! After the Pecha Kucha webinar, those who have registered for the Stakeholder Meeting will have access to all of the event's On-Demand sessions via the PSCR 2022 Mobile App. Attendees are encouraged to watch On-Demand sessions prior to arriving in San Diego.
