Braid foliation techniques provide tools for studying knots and links and related surfaces in the three-sphere. We discuss these techniques and how they can be used to study quasipositive links, an important class of links lying at the intersection of complex, contact, and symplectic geometry. In particular, we'll use recent work of LaFountain-Menasco to show that every quasipositive link has a quasipositive minimal braid index representative.
