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 MobiHoc 2017, IEEE ICC (International Conference on Communications) 2017, IEEE Globecom 2017, and IEEE WiOpt 2017.

She is an associate editor for the IEEE/ACM Transactions on Networking and the IEEE Transactions on Wireless Communication.

NEW: The updated Communication Network Analysis course will be taught next semester: SPRING 2018. Graduate students who want to educate themselves in networking concepts are strongly recommended to take this course. EE531 or equivalent knowledge of discrete stochastic processes is strongly recommended prior to taking this course.
