DESCRIPTION: The age of gravitational-wave astronomy is now in full swing:
  For the first time\, we gain observational access to the highly dynamical
  strong-field regime of the gravitational interaction. Constraining potent
 ial deviations from General Relativity (GR) requires reliable waveform pre
 dictions\, not just in GR\, but also when higher curvature corrections con
 tribute to the dynamics. I will present an overview of recent progress on 
 (i) mathematical well-posedness\, (ii) physical time evolution in the pres
 ence of ghosts\, and (iii) resulting numerical nonlinear waveforms. In com
 bination\, the above constitutes a feasible pathway to use current and fut
 ure gravitational-wave observations to constrain effective field theories 
 of gravity. Items (i) to (iii) are based on three ongoing collaborations: 
 2407.08775\, ... (with P. Figueras and A Kovacs)\; 2305.09631\, ... (with 
 C. Deffayet\, S. Mukohyama\, and A. Vikman)\; 2104.04010\, 2306.04725\, ..
 . (with H. Lim).
