Dynamic contact lines play a central role in numerous natural settings and industrial applications, yet remain one of the most challenging physical phenomena to understand and model. Arising when one fluid displaces another on a solid substrate, dynamic contact lines often yield highly nonlinear multiscale free-boundary problems whose resolution requires drawing together knowledge from fluid mechanics, interfacial phenomena, rheology, experimental measurements, and applied and computational mathematics. The purpose of this workshop is to bring together leading researchers to discuss recent progress in our understanding and modeling of dynamic contact lines and to identify promising opportunities for future research.

Please note the workshop will begin on Monday, March 26 with registration beginning at 8:15 a.m. and will end around 12:15 p.m. on Wednesday, March 28.
