Front cover picture in "Inverse Problems"
A figure from the research paper "Preconditioning Inverse Problems for Hyperbolic Equations with Applications to Photoacoustic Tomography" by Alexander Beigl, Otmar Scherzer, Jarle Sogn (JKU, Linz) and Walter Zulehner (JKU, Linz) got chosen for the front cover of the International Journal "Inverse Problems". The picture appearing at the Volume 36, Number 1 of the journal presents initial source reconstructions from Photoacoustic Tomography data.
Otmar Scherzer in ECMI Annual Report
Otmar Scherzer gave an interview to the ECMI Annual Report 2018: “Mathematics with industry: driving innovation”. He describes how the field of industrial mathematics evolved over the last years and his recent research projects, focusing on the SFB project “Tomography across the scales”. The Report is edited by A. Münch (University of Oxford) and the interview was conducted by L. Mindrinos (RICAM, Linz). You can read the whole report here.

Article in Krone newspaper "Laserblitz und Donner" by O. Scherzer

Otmar Scherzer presented in "Kronenzeitung" within the weekly column "Krone der Wissenschaft" the ideas and the scopes of the SFB project "Tomography Across the Scales". The article (in german) addresses the general principles of tomography (computed and photoacoustic). The article can be acquired on PressReader.

SFB goes to Banff, Canada

Otmar Scherzer was a member of the organizing committee of the “Reconstruction Methods for Inverse Problems” workshop in Banff, Canada, June 23-28, 2019. This workshop brought together researchers working on inverse problems coming from medical imaging, non destructive testing, computer vision and geophysics. The PI of sub-project “Quantitative Coupled Physics Imaging”, Peter Elbau and the post-doctoral researcher of the sub-project “Tomography with Uncertainties”, Ekaterina Sherina presented their recent work related to our SFB project “Tomography Across the Scales”.

Reconstruction Methods for Inverse Problems (19w5092)

at Banff, Alberta from Sunday, June 23 to Friday June 28, 2019


  • Elena Beretta (NYU Abu Dhabi & Politecnico di Milano)
  • Uri Ascher (University of British Columbia)
  • Otmar Scherzer (University of Vienna)
  • Luminita Vese (University of California, Los Angeles)


Inverse problems require to determine the cause from a set of indirect observations. Such problems appear in medical imaging, non destructive testing of materials, computerized tomography, source reconstructions in acoustics, computer vision and geophysics, to mention but a few. The 21st century is the golden age of computer imaging: Measurement devices have become enormously powerful and huge amounts of data are recorded at every eye glimpse. Moreover, computer technology has developed to such a high degree of efficiency that the evaluation of such an enormous amount of data has become possible *if* adequate mathematical and computational tools are used.

Recently, the community has been exposed to fundamentally new mathematical models (such as learning), which stimulated exciting theoretical developments and new computational algorithms for solving complicated large scale inverse problems. This workshop will survey modern and identify new mathematical and computational developments for tackling such problems.

Otmar Scherzer receives the 2018 EAIP award

The Eurasian Association on Inverse Problems (EAIP) is a non-governmental organization working to ensure a coordination between inverse problems research groups and scientific schools in Eurasian countries, by providing international conferences, meetings and summer schools on inverse problems, both in theory and applications.

The association has established an "EAIP Award" to recognize outstanding scientific contributions to the field of inverse problems and continuous efforts to foster cooperation between researchers of Eurasian countries.
