Research Overview

Consisting of a large number of intricately connected neurons, the brain is one of the most sophisticated dynamical systems in nature. Understanding how the brain computes is at the forefront of current scientific research. Research in our group focuses on theoretical analysis of biological neural networks and computational models of song generation in songbirds, speech recognition in humans, and learning and memory in the hippocampus. The modeling is done in close collaboration with experimental groups.
