Diffusion in Biological Media

Remarkable progress in advanced microscopy has yielded unprecedented access to a path-wise observation of the diffusive behavior of bacteria, viruses, organelles and various invasive particulates in biological fluids. Upon inspection of the data one immediately notes, "That's not Brownian motion!" Perhaps not surprisingly, media such as human mucus are highly heterogeneous and exhibit significant viscoelastic properties. In this talk, I will provide a survey of recent experimental observations along with mathematical models that are currently in use. Wherever possible I will point out open problems in this burgeoning area of research.
