The main questions of our group are: How do cells sense, process information and take decisions? How is information shared among cells and used to orchestrate collective behaviors, for example during embryonic development or in adult tissues?
We are interested in the mechanisms that control information processing at different levels of biological organization. We approach these questions using model systems from developmental biology, embryonic stem cells and neuronal microcircuits, establishing close collaborations with experimental labs.
We employ theoretical approaches to study the dynamics of cellular information processing at the molecular, cellular and tissue levels. We are also interested in how different levels of biological organization are connected, and how they mutually regulate each other. We use and develop methods from dynamical systems theory, stochastic processes and out of equilibrium statistical physics.
