Jakob Heide Jørgensen
PhD student
Since October 2009 I have been studying for the PhD degree at the Technical University of Denmark, where I belong to the
Scientific Computing Section under the
Department of Informatics and Mathematical Modelling.
The PhD project is partially funded by the Danish Research Counsil for Technology and Production Sciences (FTP) through the
project CSI: Computational
Science in Imaging. The project is supervised by Prof. Per
Christian Hansen,
Department of Informatics and Mathematical
Modelling, Technical University of DTU.
I obtained my MSc degree in 2009 with the Master's thesis Knowledge-Based Tomography Algorithms,
(supervisor: Prof. Per Christian Hansen,
Department of Informatics and Mathematical
Modelling, Technical University of DTU, co-supervisor: Research Prof. Henning Friis Poulsen, Center For Fundamental
Research: Metal Structures In Four Dimensions, Materials Research Division,
Risø DTU - National Laboratory for Sustainable Energy).
I obtained my BSc degree in 2007 with the Bachelor's thesis Frames and Their Application on Robust Signal
Transmission, (supervisor: Professor Ole Christensen,
Department of Mathematics, Technical University of Denmark).
Research interests
Reconstruction algorithms for medical imaging -- in particular Computed Tomography
Optimization theory and algorithms -- in particular large-scale convex optimization
Inverse problems
