We study the stochastic counterparts of nonlinear dynamical problems such as fully developed turbulence, transport through porous media, theory of whirlpools, waterspouts and tsunami waves, stochastic magneto-hydrodynamics, turbulent transport in crossed fields, self-organized criticality, dynamics of accelerated wrinkled flame fronts advancing in a wide canal.

Many neighborhoods are cut off from other parts of the city by poor transport links and haphazard urban planning, which can often lead to social ills. Urban planners have often failed to take such isolation into account when shaping the city landscape, not least because isolation is difficult to quantify in the complex fabric of a major city. Random walks on spatial city graphs spot hidden areas of geographical isolation in the urban landscape.

Interactions between humans via speech, music, and body language (dance) constitute the unifying theme of research in modern communication technologies. Music, language, and dance, even though highly flexible and versatile, nonetheless might be modular in nature, being comprised of individual stereotypical building blocks programs that cannot be intentionally stopped before their completion. The profound link between action and perception in communication through language, music, and dance might be attested on the ground of mathematical communication theory, studying the problems of signal transmission, reception, and processing.
