Title:     Properties of excited hadrons from lattice QCD

Abstract: Over the years the determination of ground state hadron masses from
lattice QCD has continuously improved. While these states are a good
benchmark for lattice calculations, a large number of hadron excitations
are known and it would be desirable to calculate their properties from
first principles. This turns out to be a highly non-trivial task, as
excited states only contribute as sub-leading exponentials to Euclidean
correlation functions. In this talk I will briefly describe one possible
method for the calculation of excited state properties and present
results for both light-quark mesons and charmonium. In addition, I will
present some (preliminary) results for baryon axial charges.
