Neutrino Flavor Oscillations without Flavor Mixing (with K. Dienes), hep-ph/0008144, Phys. Lett. B500, 133 (2001).

We propose a model with large extra spacetime dimensions which despite the fact that the physics on the brane is flavor-diagonal, the bulk neutrino theory is flavor-neutral, and the brane/bulk couplings are flavor-blind has large neutrino flavor oscillations. We discuss several phenomenological aspects of the ``bulk-mediated'' neutrino oscillations inherent in this model.
