Theoretical and Computational Neuroscience, Information Theory, Network Science

We aim to develop optimality theories that explain experimentally-measured properties of neural systems, often drawing on approaches from information theory and network science. Further, we try to develop mathematical models of associative memory and creativity. We are specifically interested in analyzing connectomics datasets to understand principles of neural computation. We also do some work in neuroengineering to develop better ways to sample neural spike trains and to reconstruct connectivity patterns from multielectrode stimulation experiments. We are recently intrigued by the neural correlates of cognitive training.
