Modern experiments require sophisticated analysis tools for
interpreting and extracting interesting physics from their data. For
hadronic and/or nuclear reactions, such analysis tools are often
theoretical models constructed with hadronic degrees of freedom. As
such, I discuss a dynamical coupled-channels model developed for
analyzing meson-baryon reaction data, thereby extracting baryon
resonances. This dynamical model also has a great potential, with some
extensions, for analyzing J-PARC data, and studying strange nuclear
physics. I will discuss our ongoing effort towards this direction.
