Physics of Living Systems Group


The research in our group focuses on the physics of living systems. We study dynamic processes at the cellular and tissue scales and their role during morphogenesis, namely, the process of development of an organism. To do this, we use theoretical methods from equilibrium and non-equilibrium statistical mechanics, and nonlinear dynamics.


Research Topics:

  • Active and passive transport inside cells
  • Physics of morphogenesis
  • Collective phenomena in biological active matter
