Tetraquark bound states and resonances using constituent quark models, complex scaling, and diffusion Monte Carlo — including fully heavy $QQ\bar{Q}\bar{Q}$ states.

Coupled-channel dynamics for the $X(3872)$ pole structure, virtual states, and three-body molecular states like $D{D}^{\ast }{\bar{K}}^{\ast }$.

HBχPT calculations of polarizabilities for spin-$\frac{1}{2}$ and spin-$\frac{3}{2}$ singly heavy baryons and heavy triplet hadrons.

Branching fractions in $B^{-}\to D^{-}{X}_{0,1}(2900)$ and hidden-charm strange molecular states in $B$ and $B_s$ decays.
