Phase Transitions and Scale Invariance in Biology


A Complex Systems Dynamics (CoSyDy) Meeting at Imperial College London


Venue: Lecture Theatre 2.28 in the Royal School of Mines, Department of Bioengineering, Imperial College London, South Kensington Campus, London

Time and date: 1-5pm, Monday, September 28, 2015

Organisers: Chiu Fan Lee (Bioengineering) & Gunnar Pruessner (Mathematics)

Biologists have recently discovered that a cell may be using the physical mechanism of phase separation to organise its membrane, cytoplasm, and nucleoplasm. The phenomenon of phase separation is based on equilibrium thermodynamics while living organisms operate in the far from equilibrium regime. How do we put an equilibrium phenomenon in an nonequilibrium context? This meeting aims to bring researchers from both physical and life sciences together to further our understanding of phase transitions observed in biology.
