Current Research Interests:

My research interests fall in the general field of communication networks (particularly wireless ad-hoc networks and sensor networks), cyber-physical systems with applications to smart grid, stochastic modeling and optimization, and wireless communications. Together, these areas have a wide range of intellectual emphasis. I believe that to make great impact, engineering research should be application-driven and high-quality research should bridge theory and practice, and researchers should build a broad spectrum to follow the cutting-edge applications and meet the demands therein.

My research draws on a synergy of advanced mathematical tools to deliver practical network solutions. Recent research activities in our group include characterizing delay peformance of wireless networks via fluid analysis and heavy traffic diffussion approximation, using optimal stopping theory to devise PHY-aware distributed scheduling for ad-hoc networks, investigating the impact of noisy feedback on stochastic network utility maximization for QoS provisioning, joint MAC design and routing for MIMO ad-hoc networks, self-similarity of multi-access interference and resource allocation in wireless CDMA networks, throughput scaling and power allocation in ad-hoc/sensor networks, capacity bounds of MIMO relay channels, Large system analysis of CDMA networks, rate distortion theory, and a complex network view of ad-hoc/sensor networks. Notably, our research group is among the first few groups in two areas: 1) cross-layer optimization and 2) wireless relay networks; and our research results in these areas have been well received.

Traditionally, researchers in networking research and information theory investigate research problems using "different languages". The fast growing area of wireless networks (particularly network optimization and network information theory) serves as a nice bridge between these two communities. Since Fall 2000, we have carried out research on cross-layer optimization and control for different network models, including wireless cellular networks, ad-hoc networks and sensor networks. Given that cross-layer optimization was a relatively new open research area, I organized a panel on ``Defining cross-layer design in wireless networks'' at ICC 2003.
