Research Field

Our research is within the field of Computational Neuroscience. We utilize computer models to explore how information is processed in the brain and how the brain circuits adapt to the environment. Drawing on analytical techniques from statistical physics and information theory, we probe the key functional properties of neural circuits. We apply these techniques to distill diverse experimental findings into a few core concepts. We hold a particular interest in activity-dependent forms of plasticity in the brain, which exert significant influences on learning, memory, and development. Leveraging mathematical models, we aim to formulate a theory that bridges cellular-level plasticity rules and computation. The capacity of neurons to represent and retain information is gauged from the structure and behavior of resulting circuits.
