I present the main lines of the research I would like to develop
 in the next years. It concerns the analysis of amplitudes for hadron
 spectroscopy. One of the main goals of the GlueX, but also CLAS12,
 experiments is the discovery of new resonances which could be only
 achieved with a detailed analysis. I sketch the steps of such analysis
  based on Regge theory taking the reaction \gamma p \to \eta \pi p as
 an example. I also explain how a systematic implementation of theoretical
 amplitudes could be realized with the amplitude generator MadGraph.
