>> Excited Hadrons From Data 
>> 
>> Mapping out the spectrum of excited hadrons from data is a cornerstone to the
>> understanding of the strong interaction. With the advent of high-precision photo 
>> and electroproduction data from JLab and other facilities, and the future data 
>> from GlueX, there is finally the chance to come to more conclusive answers
>> regarding the resonance content. One challenge on this path is to combine the
>> data of different reactions in a global analysis while respecting unitarity, analyticity, 
>> gauge invariance and other theoretical requirements such as chiral constraints. 
>> I will present recent results of the analysis of photon and pion-induced reactions
>> that allow for the reliable extraction of resonance poles and residues. Special 
>> emphasis will be placed on future challenges in the analysis of excited mesons 
>> and the interconnections to baryon analysis. Universal principles like coupled-
>> channel unitarity even apply to the analysis of upcoming data of resonances 
>> decaying in the finite volume of lattice simulations.
