Research Interests: 

Physics of Living Systems Group

 

The research in our group focuses on the physics of living systems using theoretical and computational techniques. We study biophysical 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 methods from non-equilibrium statistical mechanics and nonlinear dynamics.

 

Research Topics:

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