February 16, 2018 - Our paper "High reflectivity metamaterial of close-packed dielectric spheres," has been published in Journal of Optics. (manuscript)
December 29, 2017 - After nearly 10 years of work and 7 rejections, my paper on quantum gravity is finally published. The basic idea is to allow off-shell virtual gravitons to obey higher-derivative equations of motion while requiring on-shell gravitons to obey Einstein's field equations. This leads to a theory that is both renormalizable and unitary. (manuscript)
