Overview:

Our research aims to characterize multi-scale normal and abnormal brain dynamics, with the ultimate goal to improve our understanding of the neural mechanisms underlying behavior as well as to identify robust neural signatures of neurological disorders/diseases. To achieve these goals we develop novel computational (signal processing and statistical) methods and mathematical models for the analysis of high-dimensional electrophysiological and imaging data. Our research activities lie at the intersection of neuroscience, electrical engineering, applied mathematics and statistics.

Current Projects: 

  • Robust characterization of brain networks and their dynamics in the typically developing human brain during the first few years of life using large longitudinal electrophysiological (EEG) datasets
  • Identification of novel neurophysiological signatures of seizure dynamics and more broadly the epileptic brain
  • Multi-scale characterization of the impact of repeated sleep restriction and recovery on brain dynamics and associated cognitive performance.

This work is supported by the National Science Foundation, the National Institutes of Health and Harvard Catalyst.
