SUMMARY:Colloquium: Rosemary Braun: "How to Have the Time of Your Life"
UID:642190@northwestern.edu
TZID:America/Chicago
DESCRIPTION:For many organisms\, timing is a literal matter of life and death: survival depends on foraging\, hiding\, sleeping\, reproducing\, and developing at the right time.  Autonomous intracellular oscillators -- biological clocks -- are a remarkable solution to this problem.  By providing a shared temporal reference\, they coordinate processes across spatially extended systems without the need for constant costly signaling\, and allow organisms to anticipate environmental changes rather than merely react.  From a physicist's perspective\, they also raise fascinating questions: how do living clocks generate stable rhythms from noisy molecular components\, synchronize to weak environmental cues\, and reliably encode information over long timescales?  In this talk\, I will use biological timekeeping as a framework for broader questions in physics about oscillators\, entrainment\, synchronization\, multiscale adaptation\, and the tradeoffs among precision\, robustness\, flexibility\, and energetic cost in nonequilibrium systems.  I will discuss how stochastic models of intracellular dynamics can illuminate the stability of bacterial clocks; how Kuramoto-type models of physiological synchronization can provide insights into human health; and how dynamical information can be extracted from noisy\, sparsely sampled\, and not-strictly-periodic time-series data.
