Virtual symposium on
Physics of Dense Suspensions
July 9-10, 2020
Sponsored by the Journal of Rheology
Meeting Organizers
The symposium will serve as a forum for presentation and discussion of recent developments in the rheo-
physics of dense suspensions. Four themed sessions will be focused on papers from the Journal of Rheology special issue: “Physics of Dense Suspensions”
Meeting discussions and pre-submitted questions and author responses will be collected and edited for publication in a future issue of the Journal of Rheology. We are now accepting question for individual papers’ discussions that can be submitted at:
