Stochasticity is unavoidable when considering biological systems and processes, both at the macro scale with populations surviving in rapidly and unpredictably changing environments, but also and especially at the molecular level, where entropic considerations can have significant implications. Not only must systems be robust but some systems actually rely upon Brownian motions in order to operate efficiently. The workshop will address topics from the spread of diseases, the dispersal of species in spatially random environments, neuronal acivity (singly and in networks), genetic evolution, cellular locomotion, wound healing, genetic regulatory systems, among other things.
