My research interests include network information theory, wireless communications, localization and navigation, security and privacy. My current and past research topics include:

• Physical layer algorithm design for 5G sub-6GHz, mmW & RedCap

• Machine learning for high-precision localization in wireless networks 

• Fundamental limits of treating interference as noise

• Fundamental limits of zero-forcing for MIMO networks

• Power control and link scheduling for D2D networks

• Interference alignment and topological interference management

• Physical layer secrecy for wireless networks

• Transceiver design for IEEE 802.11ax OFDMA WLAN

• Transceiver design and RLT implementation for UWB systems

I am particularly interested in understanding the fundamental limits of multiuser wireless networks and deriving design principles for real-world networks based on theoretical insights. An example is my previous research on the optimality of treating interference as noise from a generalized degrees-of-freedom (GDoF) perspective. The insights obtained from the GDoF study not only lead to nice theoretical results, e.g., the capacity within a constant gap for any finite SNR, but also motivate distributed and low-complexity algorithms for power control and link scheduling.
