DESCRIPTION:\n	Abstract\n\n	In this talk\, I will review our recent work a
 nd its attempt to extend the scope and predictive power of the stochastic 
 formalism for inflation. After briefly introducing our gauge-invariant coa
 rse-graining procedure\, I will discuss our formulation of stochastic dyna
 mics in full General Relativity\, including all metric and scalar matter d
 egrees of freedom\, as well as gradient contributions. I will then present
  numerical implementations of these stochastic equations within the framew
 ork of Numerical Relativity\, demonstrating their efficacy in well-underst
 ood scenarios and their application to ongoing investigations.\n	With this
  framework fully established\, I will show how the formalism can be genera
 lised beyond General Relativity\, in particular to scalar–tensor theorie
 s of dark energy and multifield scenarios\, and potentially beyond.\n	Fina
 lly\, if time permits\, and given the newly unlocked possibility of studyi
 ng near-horizon phenomena and broader classes of theories\, I will conclud
 e by discussing how one can identify the stochastically relevant regions o
 f spacetime.\n\n	Link to Zoom registrationhttps://zoom.us/meeting/register
