This workshop brought together experts in Effective Field Theory (EFT), gravity, and fluid dynamics to foster interdisciplinary collaborations. Sample topics interfacing EFTs, gravity, and fluid dynamics included: New insights in gravitational thermodynamics and gravitational EFTs; Causality constraints on gravitational and hydrodynamic EFTs; The fluid-gravity correspondence; Mathematical aspects of well-posed formulations of non-ideal fluid dynamics in general relativity.
