Professor Tom Luo's general research interests include the theory, design and analysis of efficient optimization algorithms with application to data communication, wireless and optical networks and systems, and signal processing.

He is especially interested in computation/communication complexity issues arising from these problem areas. This includes both providing theoretical lower bounds on the complexity and designing efficient methods whose complexity closely match the lower bounds. His current research interest lies in the theory of multi-user communications and the application of optimization techniques to the design of multi-antenna communication systems.
