Niclas Björsell

Senior lecturer

Research subject: Elektronik

Niclas Björsell received his B.Sc. in Electrical Engineering and his Lic. Ph. in Automatic control from Uppsala University, Sweden in 1994 and 1998, respectively; he received his Ph. D. in Telecommunication from the Royal Institute of Technology, Stockholm, Sweden, in 2007. In 2012 he was appointed Docent in Telecommunications at the Royal Institute of Technology, Stockholm.

For more than 25 years he has hold positions in the academy as well as in industry. He has almost 20 years of experience from research and development projects; both national and international and mainly in collaborations between industry and the academy. He is currently Associate Professor at the University of Gävle and program director for the study program in Automation Engineering. He has published more than 80 papers in international peer-review journals and conferences, and his research interests include radio frequency measurement technology, analog-to-digital conversion, non-linear systems, wireless communication and automation.

Dr. Björsell is Associate Editor of IEEE Transactions on Instrumentation and Measurement, reviewer for several journals and conferences, and voting member of the Waveform Generation, Measurement and Analysis Committee (IEEE, Instrumentation and Measurement).

CURRENT RESEARCH

Currently, Niclas Björsell is involved in two research projects, one within wireless communication for automation systems and one within medical measurement technology.

Industrial Automation and Millimeter Waves

The project comprises four work packages, of which Dr. Björsell is responsible for (i) Radio communication in industrial environments and works actively in (ii) Process automation and wireless communication. The others are (iii) Measurement technology for components and (iv) Industrial measuring technology. In the field of Radio Communication in Industrial Environments, measurements in the 24 GHz band are carried out in industrial environments in order to develop channel models, measure the impact of disturbances and study doppler effects from moving objects. Process Automation and Wireless Communication aim to combine wireless communication and control technology. In addition, modeling techniques are used to create digital twins that can be used, for example, to detect a maintenance need.

Instrument for High-Speed Electron Tunneling Measurements

The project aims to develop a measuring instrument to sequence DNA and RNA.
