Professional Background

Optimization, signal processing for communications

Research Interests

My general research interests include the design and analysis of efficient optimization algorithms in data communication and signal processing. I am 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. My current research interest lies in the theory of multi-user communications and the application of optimization techniques to distributed signal processing.
