Background and activities

 

Yun Ai is a PhD student working at the Norwegian University of Science and Technology, NTNU, under the direction of Prof. Michael Cheffena (NTNU) and Prof. Josef Noll (University of Oslo, UiO). The PhD position is affiliated with the Department of Informatics, UiO. He received his Master's degree in Electrical Engineering from Chalmers University of Technology, Sweden.

Prior to the PhD studies, he has also been at the Technische Universität Darmstadt, Germany as a research student and Ericsson as an engineer. During the summer of 2016, he was a visiting researcher at the Keio University in Tokyo, Japan. In the winter of 2016, funded by a stipend from the Norwegian University Center in St. Petersburg, he visited the Saint Petersburg State University, Russia to research on the game theory.

His current research work focuses on radio propagation modeling, wireless sensor network, and smart grid. Besides research, he is also responsible for teaching and tutoring of the master level course at NTNU: TØL4101: Wireless Industrial Communication.
