I will discuss some recent progress in studying hadrons using first-principles lattice QCD calculations. The spectroscopy and interactions of hadrons probe the strongly-interacting regime of QCD, and in recent years experiments have observed a number of puzzling
hadrons that challenge our understanding of the strong interaction. Lattice QCD provides a method for performing first-principles computations of the properties of hadrons and hence a QCD-based understanding of the phenomena. However, the majority of hadrons
are unstable -- they decay strongly and appear as resonances in hadron-hadron scattering -- and lattice calculations of these are challenging. I will summarise recent advances in this area and present some applications in the heavy-meson sector, including
calculations of $D\pi$, $DK$, and $D\bar{K}$ scattering relevant for the $D^*_0(2300)$ and the enigmatic $D^*_{s0}(2317)$.</div>
