Sara Aviyente
Associate Professor
Research Biography

Her research focuses on the theory and applications of statistical signal processing, in particular non-stationary signal analysis. She is interested in developing methods for efficient signal representation, detection and classification. Dr. Aviyente is also interested in the applications of signal processing to biological signals such as the analysis of event related brain potentials. Her current research focuses on the study of the functional networks in the brain.
