When atoms and molecules interact with intense x-ray pulses, they are highly ionized via a sequence of photoionization events and accompanying relaxation processes, so-called x-ray multiphoton ionization. Resonances that could occur during this multiphoton multiple ionization dynamics will dramatically influence formation of those highly charged ions. In my talk, I will discuss how to describe sequential multiphoton multiple ionization dynamics in the x-ray regime, emphasizing resonant excitation, and how to overcome theoretical and numerical challenges in doing so. I will present two examples of resonance-related phenomena observed in recent XFEL experiments: REXMI and REMPI in the x-ray regime.
