Robustness in minimal models of biochemical oscillators

Biochemical oscillations are ubiquitous in biology and allow organisms to properly time their biological functions. Two biologically relevant observables in these biochemical oscillator circuits are the coherence and time period of oscillations. In this talk, I will discuss minimal Markov state models of non-equilibrium biochemical networks that support oscillations. In particular, I will discuss how a high energy consumption budget can make these quantities robust in a variety of settings.

Flocks and crowds: a Gulliver travel

For centuries, applying an external pressure difference has remained the only solution to flow a liquid in a pipe. Over the last ten years, by engineering soft materials from self-propelled units, we have learned how to drive fluids from within. In the first part of my talk I will show how to assemble spontaneously flowing liquids from interacting colloidal robots. I will then show how to infer the hydrodynamics of these active fluids from the sole inspection of their fluctuation spectra. In the second part of my talk I will show that the same concepts and tool can be effectively use to account for the flows of pedestrian crowds walking on the streets of a windy city.
