Abstract: Charm physics, involving a heavy up-type quark, offers a pathway to search for new particles and couplings beyond the Standard Model complementary to that of B physics. A program based on precision measurements of charm lifetimes is now underway at Belle II, and benefits from the detector`s outstanding vertexing performance and low-background environment. Recent results from measurements of D_s meson and Omega_c baryon lifetimes are presented. In addition, a novel algorithm to identify the flavor of neutral charm mesons is presented that effectively doubles the sample size for many measurements of CP violation and flavor mixing.
