Disha Gupta, Ph.D.

My training has been in advanced digital signal processing techniques, especially applied to neurophysiology. I have experience in feature extraction from various types of biomedical signals such as electrocardiography, electroencephalography, magnetoencephalography and electrocorticography. I have applied a combination of qualitative and quantitative methods for applications such as investigating the spatio-temporal dynamics of seizure onset, seizure prediction, localization of cortical seizure foci, real-time decoding of cognitive tasks such as movement planning and execution and auditory processing. I have also briefly applied compression and encryption to digital biomedical signals for body area networks. Techniques such as of blind source separation, neural network analysis, source localization and linear and nonlinear connectivity measures for causality, have been quite useful for the above research. My research interests and future goals are investigating the cognitive challenges in autism (and epilepsy) and exploring biomarkers, and / or interventions for assisting or enhancing the cognitive limitations (if any) for children with autism, especially those who also have epilepsy.
