Research Interests

Signal and data processing, information theory, and their applications to wireless communication with a focus on the interplay of communication systems and networks; including network coding, user cooperation, spectrum sharing, opportunistic access, and scheduling with different delay constraints as well as millimeter wave communications.

Signal and data processing, information theory, and their applications to neuro-engineering with foci on (i) modeling neuronal circuits connectivity and the impact of learning on connectivity (ii) real-time closed-loop stabilization of neuronal systems to mitigate disorders such as epilepsy, Parkinson, depression, and obesity, (iii) developing an understanding of cortical representation and fine-grained connectivity in the human language system and on building microelectronics with large data analysis techniques to develop a fine-grained recording and modulation system to remediate language disorders.
