Academic Background

Günther Koliander received the Diploma degree in Technical Mathematics (with distinction) from TU Wien, Austria, in 2011 (Diploma thesis “Hilbert Spaces of Entire Functions in the Hardy Space Setting”). From 2011 to 2017 he was with the Institute of Telecommunications, TU Wien, Austria, where he finished his PhD (with distinction) in the WWTF project NOWIRE in April 2015 (Dissertation "Information-theoretic analysis of noncoherent block-fading channels and singular random variables"). He twice held visiting researcher positions at Chalmers University of Technology, Gothenburg, Sweden.

Since July 2017 he is part of the Acoustics Research Institute's workgroup "Mathematics and Signal Processing in Acoustics", where he works on information-theoretic topics and compressed sensing methods.

Current Research

His main interests include information theory, point processes, and compressed sensing.

Current topics:

  • Rate-Distortion theory for point processes
  • Entropy for integer-dimensional singular random variables
  • Source coding for general sets and measures
  • Lossless analog compression
