abstract
The study of the spectrum of excited states of the nucleon is vital to our understanding of how QCD is realized in the baryon spectrum. Using a simultaneous analysis of the pion nucleon scattering data up to 2 GeV as well as the results of lattice QCD calculations, we obtain new insight into the nature of the Roper resonance as well as the excited states around 1.9 GeV.

Non-diagonal DVCS and studies of hadronic structure with $N \to N^*$ transition GPDs
A proceedings review of transition GPDs for non-diagonal DVCS: model estimates for JLab@12 GeV, a qualitative match to CLAS BSA data, and spin-J Froissart-Gribov projections for resonance spectroscopy.
