In her work on dynamic spectrum management and cognitive radios, she has studied the effectiveness of node collaboration. She has developed analytical results and protocols to address both explicit coordination via local negotiations, and implicit coordination via independent adjustments following network enforced rules. Her current research interests include protocol and algorithm design in dynamic spectrum networks. She was selected as one of the MIT Technology Review's TR35 for her work on cognitive radios. Her work was also featured in MIT Technology Review's 10 Emerging Technologies of 2006.
