Our group studies the physics of imaging and new methods of imaging physics. Examples include optical hydrodynamics, in which the propagation of light is described in terms of fluid flow, statistical physics using incoherent light, and optics in phase space. The new language allows optical modeling and observation of material behavior that is difficult, if not impossible, to see by other means. It also provides a framework for the discovery of new photonic effects.


Computation, materials science, and topology are revolutionizing imaging. Unlike direct imaging with lenses, or post-processed photo editing, we are combining wave dynamics and numerical techniques in an integrated approach. The results run counter to intuition from traditional optics, e.g. sharper pictures from defocused waves and improved signal detection/quality by adding noise. Specific fields of interest include microscopy, computational photography, and biomedical imaging.
