Our research has focused on opportunistic spectrum access (OSA) in the context of cognitive radio networks (CRNs). We have been interested in development and performance evaluation of methods for detection of primary user (PU) activity whether by a single secondary user (SU) or through collaboration among a number of such users. We have also worked on developing and optimizing OSA mechanisms that maximize SU throughput subject to an upper bound on the interference caused for PUs using the ROC curves characterizing the performance of the PU detection scheme. Along the same lines, we are interested in exploiting location information for OSA as well as developing pricing mechanisms that regulate OSA and coexistence of PUs and SUs.

More generally, we are interested in any aspect of OSA and CRNs including but not limited to power control, MAC layer protocols, quality of service (QoS), and routing.
