Background and activities

Stefan Werner is a Professor at the Department of Electronic Systems. He is a member of the Signal Processing Group. He is also an Adjunct Professor with Aalto University in Finland, a visiting Melchor Professor with the University of Notre Dame in the US, and an Adjunct Senior Research Fellow with the Institute for Telecommunications Research, University of South Australia. Professor Werner has an M.Sc. from the Department of Electrical Engineering at KTH Royal Institute of Technology in Sweden and a D.Sc. (with honors) from the Department of Electrical and Communications Engineering at Helsinki University of Technology in Finland.

Open Positions

I have one postdoctoral position related to distributed machine learning with applications in future wireless systems. Drop me a line if you have any questions, especially if you are interested in learning in wireless systems, graph signal processing, distributed optimization, federated learning, or privacy-preserved learning.

Postdoctoral researchers may also consider applying for an ERCIM Fellowship; please let me know in advance if you intend to apply.

Research Interests

  • Graph signal processing and graph neural networks
  • Distributed and federated learning
  • Privacy-preserving learning
  • Wireless communications
  • Adaptive signal processing and machine learning
  • Internet of things
  • Physical-layer security and privacy
  • Smart grids

Areas of Expertise

Wireless communications, statistical signal processing, graph signal processing, adaptive filtering, and learning. In these areas, he has published roughly 200 scientific journals and conference publications.

He has extensive credentials and experience in advancing theory and applications of set-membership adaptive filtering and adaptive networks, which offer viable solutions to event-triggered sensing, processing, and communication in wireless sensor networks. In this area, he has developed and analyzed new approaches that feature reduced internode communication.

His research within wireless communication includes, e.g., analysis and design of full-duplex relaying, MIMO communication, and RF impairment modeling and compensation. The early publications on full-duplex relaying are highly cited and have opened up a new research area that has been very active during recent years.

More recently, he has looked into the development of CPS/IoT technologies, particularly those relevant to advancing the communication and control, security and privacy, and networking of the data collection infrastructure.
