AB  - In order to probe the nature of the strong interactions in the medium-energy regime, where a perturbative expansion of QCD is not possible, the spectrum of excited baryons provides important information. Over the time, different approaches have been developed to connect predictions from quark models or lattice calculations to experimental data. Among those, dynamical coupled-channel models are especially suited for a simultaneous analysis of multiple reactions with different initial and final states. Unitarity and analyticity are preserved which allows for an extraction of resonance parameters in a well defined way, i.e. in terms of pole positions and residues.I will give an introduction into the framework of the so-called Jülich-Bonn dynamical coupled-channel model, and present results of a combined study of pion- and photon-induced hadronic reactions.Recently, the approach was also extended to electroproduction reactions.
