Dynamics of complex interfaces is investigated in a model of an oscillatory medium. The moving interfacial zone separating two phases of homogeneous oscillation consists of a phase with chaotic spatial and temporal behavior. As system parameters vary, the thickness of the interface grows until a phase transition occurs where the chaotic phase fills the entire domain. The system behavior and its critical properties are analyzed in terms of two coupled stochastic equations describing the profiles that delimit the interfacial zone.
