16th SFB Internal Meeting in Strobl

From 1 to 5 July, the 16th SFB internal meeting was held in a nice venue at Wolfgangsee lake in Strobl. The summer meeting between SFB members is an opportunity to share recent progress in the eight different projects and future research directions. We were honoured to have three internationally renowned professors as invited speakers, Markus Grasmair, John Schotland, Ivo Ihrke, Andrea Aspri and Alina Boecker along with researchers and PhD students from Austrian institutions of excellence (RICAM, University of Vienna) and Germany.

During the meeting, we celebrated the 60th birthday of one of the SFB project leaders, Professor Otmar Scherzer.

Professor Otmar Scherzer is an internationally recognised mathematician known for his work in the fields of applied mathematics, particularly in inverse problems, imaging, and numerical analysis.

SFB goes to the 11th IPMS 2024

Two of our SFB members, Peter Elbau and Otmar Scherzer, together with team members from the Computational Science Center (CSC) of the University of Vienna and the Johann Radon Institute for Computational and Applied Mathematics (Ricam), Linz, attended the 11th International Conference “Inverse Problems: Modelling and Simulation” (IPMS 2024) in Malta as invited speakers to mini-symposia. The conference, one of the most prominent in the field, aims to bring together scientists working on inverse problems with different areas of expertise, such as mathematics, physics, engineering, computer science, medicine, and material science to provide a fruitful ground for discussion on the latest advances in theory and foster interdisciplinary collaboration.

Otmar Scherzer gives talk in celebration of 20 years of RICAM and the 70th birthday of Prof. Heinz W. Engl

SFB Speaker Otmar Scherzer gave a talk on Newton methods for solving linear inverse problems with neural network coders at a colloquium in Linz which celebrated the 20th anniversary of the Johann Radon Instute (RICAM) and the 70th birthday of its founder, Prof. Heinz W. Engl.

Prof. Heinz W. Engl also gave an interview in which he was asked about how research has developed since his inception of the institute and what his own personal research highlights are, the transcript for which may be found here.

There, SFB member Fabian Hinterer gave a talk on “a projected Nesterov-Kaczmarz approach to stellar population distribution reconstruction in Extragalactic Archaeology” in the presence of experts spanning the various mathematical branches that are connected to inverse problems. Other SFB members were also participants, including organisers Otmar Scherzer and Ronny Ramlau, as well as Peter Elbau, Michael Quellmalz, Ekaterina Sherina, Simon Hubmer and Kemal Raik.

SFB Members at the RICAM – Special Semester

From 10th to 21st of October, the first two workshop-weeks of the RICAM Special Semester “Tomography across the Scales” took place at the Johann Radon Institute for Computational and Applied Mathematics in Linz. There, Fabian Hinterer, Simon Hubmer, Michael Quellmalz, Ekaterina Sherina and Leopold Veselka, all members of the mathematical subprojects within the SFB project, were invited to present their latest scientific advances to an audience of experts in the various fields of Inverse Problems.
Furthermore, the members got the chance to exchange ideas with other researchers and to benefit from external input.
We express our gratitude to the organizers for the invitation and the hospitality during these perfectly organized workshops!

SFB at the RICAM – Special Semester

Currently, the autumn school as part of the Special Semester “Tomography Across the Scales” takes places at the RICAM in Linz. Peter Elbau, one of our project leaders, was invited to give an introductory lecture on the mathematics behind optical coherence tomography. The audience, including several members of SFB, warmly welcomed the intuitive and very well presented lecture on this highly complex topic.

Eleventh Internal SFB Meeting

From June 19 to 22, 2022, for the first time new and old members of the SFB project “Tomography Across the Scales” met each other in person in Roßleithen(Upper Austria). Interesting talks about the already accomplished and the possible future work helped the new members to get to know the various fields of research and initiated discussions about additional collaborations within the SFB project.
A hiking trip up to the Wurbauerkogel concluded this well organized event.

ESI Workshop: Tomographic Reconstructions and their Startling Applications

The online Workshop at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) has just started. This is a two-weeks event with more than 50 international researchers participating. 

In the first week (March, 15th – 18th), we have mainly talks from applied mathematicians presenting results on tomographic reconstructions while the second week (March, 23th – 25th) covers the practical applications of such methods in astronomy and medical imaging. See the full program here.

Registration is free. You just have to contact Peter Elbau.
