Computational neuroscience

One of the main goals of modern neuroscience is to understand how organisms adapt to their environment and what brain mechanisms subserve this process. My research focuses on the following areas:

  •  learning and memory: how does biological organisms learn and retain useful information in a dynamic world? How to model the biophysical mechanisms of learning and memory through mathematical simulations of large-scale neural systems? How do we regulate the granularity (specificity vs. generality) of what we learn?
  • visual perception: how do we perceive static and moving features/objects?
  • short-term memory and decision making: how is information reliably store in frontal cortical areas?
