Biography

Jan Østergaard received the M.Sc. degree in electrical engineering from Aalborg University, Aalborg, Denmark, in 1999 and the PhD degree (with cum laude) in electrical engineering from Delft University of Technology, Delft, The Netherlands, in 2007. From 1999 to 2002, he worked as an R&D engineer at ETI A/S, Aalborg, Denmark, and from 2002 to 2003, he worked as an R&D engineer at ETI Inc., Virginia, United States. Between September 2007 and June 2008, he worked as a post-doctoral researcher in the Centre for Complex Dynamic Systems and Control, School of Electrical Engineering and Computer Science, The University of Newcastle, NSW, Australia. From June 2008 to March 2011, he worked as a post-doctoral researcher at Aalborg University, Aalborg, Denmark.
He has also been a visiting researcher at Tel Aviv University, Tel Aviv, Israel, and at Universidad Technica Federica Santa Maria in Valparaiso, Chile.
Jan
Østergaard is currently a Professor (MSO) at Aalborg University, and Head of the Centre on Acoustic Signal Processing Research (CASPR). He has received a Danish Independent Research Council's Young Researcher's Award, a best PhD thesis award by the European Association for Signal Processing (EURASIP), and fellowships from the Danish Independent Research Council and the Villum Foundation’s Young Investigator Programme. He is an Associate Editor of EURASIP Journal on Advances in Signal Processing, and a Senior member of IEEE.
His main research interests are in the area of information theory, statistical signal processing, acoustic signal processing, rate-distortion theory, joint source-channel coding, networked control theory, networked audio and video and distributed concerts.
