ABOUT THE CONFERENCE Our conference vision is to ensure attendees leave with renewed interest in their field of expertise by exposing them to new tools and methods that make them more effective, showing them the value of membership in the RPSD communities and providing an enjoyable destination for the conference. We hope to provide an environment for tool developers, code users, theoreticians, and experimentalists to engage in productive discussions, establish collaborations, and build community in the foreground of scientific advancements and challenges in radiation protection and shielding. Through the planned technical sessions, workshops, plenary talks, and social events, we hope to provide an environment that is ideal for participants to engage in productive technical discussions, establish collaborations, and build community. Several workshops are tentatively planned: 1) GEANT, 2) MCNP6.3 Features and Tools for RPSD Applications and 3) MCNP6.3 Unstructured Mesh Geometry SCA
