I was part of the Wireless Systems Lab (WSL) with Professor Goldsmith.

-Code Design for Multi-Terminal Networks: I investigate the problem of code design for multiterminal systems by seeking fundamental design guidelines and devised examples of code constructions that approach the theoretical optimum. While many codes are known to perform well on simple point-to-point channels, the problem of designing codes for networks with a larger number of users is still an open challenge. -Information Processing in the Human Auditory System: I studied the coding and processing of information in the neuronal system using an information theoretical approach and proposed evaluation tools for cochlear implants in hearing impaired patients. I am currently exploring a vast range of practical solutions for bettering the user’s experience by improving the design of the electrical stimulations.

-Interference Channel with a Cognitive Relay: I determined the limiting rate advantages and optimal strategies for cooperation and interference management in small relay networks. Relay nodes are devices designed to extend the coverage of wireless and support multiple base stations and my results provide important design guidelines for practical systems by providing a better understanding of the fundamental role of interference in these networks.

In my doctoral thesis, I investigated the long-standing open problem of determining the largest attainable transmission rates in cooperating networks and provided crucial results on this topic. In wireless networks, neighboring devices can overhear each other’s transmissions and this key feature of the wireless medium can be exploited to implement collaboration strategies among users. This promises to drastically increase the efficiency and the reliability of wireless networks.
