We propose using a Stark interference technique to directly measure the odd-parity c_{ 0j} components of the electron sector c_{ \mu\nu} tensor of the Standard-Model Extension. This technique has been shown to be a sensitive probe of parity violation in atomic dysprosium in a low-energy, tabletop experiment, and may also be straightforwardly applied to test Lorentz invariance. We estimate that such an experiment may be sensitive to c_{ 0j} coefficients as small as 10^{ -18}.
