I am a professor at the Electrical
and Computer Engineering Department, Michigan State University. I am also affiliated with the
Communications and Signal Processing Lab at
My research focuses on the theory and applications of statistical signal processing, in particular non-stationary signal analysis. I have worked on three major areas: 1) transform based signal processing with an emphasis on sparsity-constrained feature extraction and classification; 2) signal processing methods for studying functional brain networks; and 3) statistical signal processing for fault diagnosis and prognosis for electrical drives.
More recently, my research focuses on the study of the functional networks in the brain. This research addresses the problem of quantifying the interactions across the brain by developing a comprehensive signal processing framework to study the functionality of the brain as a complex system based on electroencephalogram (EEG) data for a better understanding of psychopathologies.
