News & Announcements

Prof. Uysal-Biyikoglu is currently on the Technical Programme Commitees of: The First Workshop on the Age of Information (in conjunction with IEEE INFOCOM 2018), IEEE INFOCOM 2018, IEEE WiOpt 2018. She is an associate editor for the IEEE/ACM Transactions on Networking and the IEEE Transactions on Wireless Communication.

SPRING 2018 TEACHING:

EE532: Communication Network Analysis: A course on the most current analytical tools for the design of data networks. EE531 or equivalent knowledge of discrete stochastic processes is strongly recommended.

EE533: Information Theory: The future of networks will be data-driven and application-centric. This course teaches the fundamental tools for quantifying the information carried by the data, and efficient ways to transmit it.

Education
