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

We are looking for candidates with a background in Physics and with a strong motivation to work on theoretical problems at the physics-biology interface. Previous knowledge of biology is not required.
Ph.D. position: We currently have Ph.D. positions available in our group. Interested candidates may get in contact with me via email.
Postdoc position: We currently have a postdoc position available in our group. We seek candidates with a Ph.D. in theoretical Physics (Non-equilibrium Statistical Mechanics and/or Soft-matter Physics). The project(s) involves the study of biological processes using a combination of theory and computation. Interested candidates may get in contact with me with a CV.
Final year M.Sc/BTP Project: Please contact me via email or schedule an appointment.
Summer Project: Currently, there are no summer project positions available in our group.
