Recent results from Jefferson Lab (JLab) on the extraction of single–and double‐polarization observables in both the 1π–and 2π‐channel show their high sensitivity to resonant production amplitudes and therefore their importance for the extraction of resonance parameters. The CEBAF Large Acceptance Spectrometer (CLAS) has access to the baryon resonance (N*) form factors at high which is advantageous for the study of the dynamical properties of nucleon resonances. In anticipation of the 12 GeV energy upgrade to JLab, our group plans to extract the electromagnetic transition form factors (electrocouplings) for many well‐established excited nucleon states in the unexplored domain of The expected data on resonance electro‐couplings will allow us to systematically explore how in the strong interaction regime of QCD bare quarks are dressed with gluons and how quark cores of the various N* states emerge from QCD.
