News & Announcements

Graduate students in Communications or Computer Science related areas, who are highly motivated to do a competitive, highly cited thesis in a theoretical or applied area of networking are welcome to contact Prof. Uysal.

NEW Postdoctoral Associate and PhD Openings: Please contact the CNG lab coordinator Ms. Ayca Osunluk (aycao@metu.edu.tr).

The current focus of our research is Semantic-Aware communication and Data Freshness in next generation networks, with applications to IoT, NTN/Satellite IoT, Space Communications, and the evolving 6G standard.

This research program builds on our foundational work on the Age of Information (AoI), a data freshness metric that captures the needs of status update-based communication, of growing importance in remote monitoring/actuation and learning. A short video description of the AoI concept (in Turkish) is here: https://youtu.be/lLoDOk-Zgko

For broad impact of the goal-oriented communication and networking approaches to sustainable cities, we have formed the SUIT (Sustainable Urbanization Through Innovative Technologies) platform, funded by TUBİTAK under the 1004 program. A presentation on SUIT is here. A video description of SUIT (in Turkish) can be found here.

Current Synergistic Activities: Prof. Uysal is currently serving as

Director, SUIT (Sustainable Urbanization Through Innovative Technologies) Research Platform
Chair, METU Parlar Foundation For Education and Research
Member of Advisory Board, IEEE ComSoc Turkey Branch.
Member, IEEE Turkey Awards Committee
Member, 6G Platform.

Education

Ph. D: Stanford University; S.M.: Massachusetts Institute of Technology; B.Sc, METU

Research Interests

Information Freshness and Goal Oriented Communications for Networked Systems, in particular:
- Link and transport layer scheduling for Remote Inference, and other MTC applications, through exploiting freshness (e.g. AoI, QAoI) and other goal-oriented performance metrics (e.g. mean square error)
- The development of novel age-aware or goal-oriented random access protocol and implementation in LoRa/LoRaWAN
- IPR development for massive MTC access, routing and handover in Nonterrestrial Networks (NTN) toward 6G
Energy efficient/energy-neutral communication
- Optimal resource allocation in energy harvesting communication systems
- Implementation of energy harvesting communication systems

Since 2006, she has been with METU, and held visiting positions at OSU and MIT during 2014-2016. Her research interests are at the junction of communication and networking theories, with particular application to energy-efficient wireless networking. Dr. Uysal was elected a Fellow of IEEE in 2022 for “pioneering contributions to energy-efficient and low-latency communications”. She is a Fellow of the Asia-Pacific Artificial Intelligence Association, and of the Artificial Intelligence Industry Alliance, a recipient of the ERC Advanced Grant 2024, TUBITAK BIDEB National Pioneer Researcher Grant 2020, 2014 Young Scientist Award from the Science Academy of Turkey, an IBM Faculty Award (2010), the Turkish National Science Foundation Career Award (2006), an NSF Foundations on Communication research grant (2006-2010), the MIT Vinton Hayes Fellowship, and the Stanford Graduate Fellowship. She has been serving as the Chair of the Executive Board and the Chair of the Board of Trustees of the METU Parlar Foundation for Education and Research, and assistant director of METU YTM-MATPUM, since 2022. In 2022, she founded FRESHDATA Technologies.
