January 18 - 19, 2021 (Live presentations and discussion)
January 20 - 22, 2021 (Online viewing of presentations)
January 22, 2021 (Final discussion on scientific goals)

The main goals of this Science Workshop are:

1. Integration of beamline technologies and experimental rock deformation;
2. Identify outstanding questions and future research directions. We anticipate several white papers on new research visions based on community input after the workshop.
