My research interests lie in the areas of wireless communications and networking, with emphasis on MIMO communications, spectrum sharing, and coexistence of wireless systems. I leverage tools like optimization, signal processing, stochastic processes, and communication theory to solve wireless communications challenges.
My PhD work has centered around the development of spectrum sharing techniques for massive IoT communications. Specifically, I have investigated the coexistence of IoT devices with legacy cellular users, over the the licensed bands, and with other wireless networks operating in the unlicensed bands. In addition to my work on enabling massive IoT connectivity, I have worked on critical problems pertaining interference management and load balancing in dense 5G heterogeneous networks (5G HetNets).
During my internship at Qualcomm Research, I have had the opportunity to work on algorithm development and protocol design for coordinated multipoint (CoMP) to enable ultra-reliable low-latency communications for industrial IoT use cases. At Nokia Bell Labs, I have worked on the coexistence of 5G networks with fixed stations operating at 70GHz/80GHz and with satellite earth stations operating at 3.7-4.2GHz.
During my master's degree, my research has centered around dynamic spectrum access. Specifically, we investigated the challenges and limitations of state-of-the-art multiband spectrum sensing techniques, proposed a pragmatic cooperative sensing framework for multiband sensing, and investigated the benefits of network-wide based reconfiguration in both centralized and distributed cognitive radio networks. In addition, we have proposed new sensing algorithms, including an enhanced pilot-tone aided detector that overcomes imperfect phase synchronization and noise power uncertainty and a confidence-based generalized combining scheme for cooperative sensing.
During my bachelor's degree, I have worked on the design of an underwater wireless sensor network (WSN). We have developed a realistic channel model to understand the path loss in underwater environments, and designed a prototype that enables WSNs to use electromagnetic waves as means of communications.
Finally, I have worked on a personal project, where I have written a book on the fundamentals of signal detection and estimation.
