About

Short biography

Per Gunnar Kjeldsberg was born in Trondheim, Norway in 1966. He received his Sivilingeniør degree (MSc) in electrical engineering in 1992 from the Norwegian Institute of Technology (NTH). In 2001 he received the degree of Doktor ingeniør (PhD) from the same institution (now Norwegian University of Science and Technology, NTNU). Between 1992 and 1996 he worked as a design engineer at the company Eidsvoll Electronics AS. Kjeldsberg is now Professor at Department of Electronic Systems, NTNU. His research interests are embedded heterogeneous multi-processor systems, with a focus on multi-media and digital signal processing applications. He has participated in several national and international research projects, among them several EU Horizon 2020 projects, being work package leader in the FET-HPC project READEX and principal researcher in the LEIT project Tulipp. Currently he is supervisor in the MSCA-IF project Palmera. Kjeldsberg is Senior Member of IEEE and member of HiPEAC, a European Network of Excellence on High Performance and Embedded Architecture and Compilation. At NTNU Kjeldsberg is group leader of the Circuit and Radio Systems group and project leader for a strategic research initiative on Energy Efficient Computing Systems. Throughout his career, Kjeldsberg has cooperated closely with imec, in Leuven, Belgium, where he has been visiting researcher for nine months in all. He has also been visiting researcher at University of California, Irvine, Center for Embedded Computer Systems, at imec Netherlands at the Holst Centre in Eindhoven, and at School of Computer Science and Engineering, University of New South Wales, Sydney, Australia. Kjeldsberg has published extensively at conferences and in journals, and has been coauthor of three books in his fields of interest. At NTNU he teaches both undergraduate and graduate courses, and supervises a number of students at master and PhD level. Kjeldsberg is and has been a member of the board of directors both at the Faculty and in private companies. He is frequently used as reviewer for several international journals and conferences.
