The Directed Energy Physics Branch of the Naval Research Laboratory is seeking a post-doctoral researcher in applied mathematics or physics. The research opportunity focuses on the fundamental nature of partially coherent optical beams interacting and propagating in nonlinear or random media. Topics include theoretical modeling and experimental analysis of self-focusing, modulation instabilities, and scattering of invariant modes of light in random media.  Theory will guide experiments with ensemble simulations of nonlinear PDEs such as parabolic wave equations and analysis of associated inverse problems. The research can lead the way to mitigating randomness and develop new modes of optical beam control. Qualifications of a successful candidate include:•  ability to develop and m
