Research Interests
I am interested in applying optimization theory to the design and analysis of wireless communications and data networks. Currently, my focus is on the optimal design of non-intrusivie dynamic spectrum access schemes for secondary users, under the joint supervision of Prof. Zhi Ding and Prof. Xin Liu.
