New publication in Nature Communications combining acoustic trapping and OCT

The paper titled “Ultrasound-induced reorientation for multi-angle optical coherence tomography” by Mia Kvåle Løvmo, Shiyu Deng, Simon Moser, Rainer Leitgeb, Wolfgang Drexler and Monika Ritsch-Marte was recently published in Nature Communications.

The subprojects in Multi-Modal Imaging and Imaging of Trapped Particles joined forces and developed a novel strategy for acquiring multi-angle OCT by acoustic object reorientation.

Along with a model-based algorithm to fuse the multi-angle data from a priori unknown illumination angles, the strategy enables 3D reconstruction of samples such as embryos and organoids.  

Update June 3, 2024: We are pleased to announce that the paper published in Nature Communications was recently cited in the national newspaper Der Standard. The link to the article can be found here.

International Day of Mathematics

«Playing with Math» was the theme of this year’s International Day of Mathematics on March 14th. Several scientific institutions, including the University of Vienna, the Vienna University of Technology, and the Austrian Academy of Sciences, collaborated to explore intriguing mathematical concepts in a playful manner.

Axel Kittenberger and Noemi Naujoks demonstrated how a computer tomograph works and explained the fascinating mathematics behind it. They showcased the Origami Tomograph developed by CSC, which reconstructs a transparent 3D object from light projections. A special highlight was a quiz that encouraged participants to play the role of a tomograph and guess the underlying object from projection data.

PhD defense: Leopold Veselka

We are happy to announce that Leopold Veselka, PhD student in the Sub-project Quantitative Coupled Physics Imaging, has successfully defended his PhD thesis with the title “Reconstruction of optical parameters in quantitative optical coherence tomography” on 9th of January, 2024.

Leopold’s doctoral study was supervised by Peter Elbau, the principal investigator of the Sub-project Quantitative Coupled Physics Imaging affiliated with the Faculaty of Mathematics, University of Vienna. Congratulations from the SFB colleagues!

PhD defense: Fabian Hinterer

We are happy to announce that Fabian Hinterer, PhD student in Sub-project Tomography with Astronomy, defended successfully his PhD thesis with the title “Inverse Problems in Imaging Applications Across the Scales” on 3rd of November, 2023. A link to his thesis can be found here.

Fabian was a PhD student under the supervision of Ronny Ramlau, principal investigator of Sub-project Tomography in Astronomy, at the Industrial Mathematics Institute at the Johannes Kepler University Linz.


Members of the SFB took part in Fabian’s ceremony and presented him with a joint gift afterwards!

We congratulate!

PhD defense: Fabian Parzer

We are happy to announce that Fabian Parzer, PhD student in Sub-project Tomography with Uncertainties, defended successfully his PhD thesis with the title “Low-Rank and Scale-Space Methods for Imaging with Uncertainty Quantification” on 25th of October, 2023.

Fabian was a PhD student under the supervision of Otmar Scherzer, principal investigator of Sub-project Tomography with Uncertainties, at the Faculty of Mathematics at the University of Vienna.


Colleagues from the SFB project and the Computational Science Center gathered in the evening to celebrate with Fabian his successful defense.

We congratulate!

Sixth SFB Member Meeting

From 12th to 15th of September this year’s SFB Member Meeting took place in Wildalpen in Styria, Austria. Aside from presenting interesting topics on and related to the ongoing research, the SFB members gathered and used the opportunity to exchange with their collaborators from other projects.


The evening activities, a very informative quiz organized by Fabian Hinterer and a campfire, rounded off wonderfully this event which was perfectly organized by our member speaker Ekaterina Sherina.
We would like to thank the members for their participation at this year’s event!

SFB goes to the AIP23

In the first week of September the 11th Applied Inverse Problems Conference took place in Göttingen, Germany. Eight of our SFB project coordinators and members participated at this conference. All participants used the opportunity to present their recent and ongoing research in various minisymposia. In addition, four minisymposia at this conference were organized by Peter Elbau, Ekaterina Sherina, Michael Quellmalz and Leopold Veselka.

SFB Members at the ICIAM23

Two SFB members, Fabian Hinterer and Leopold Veselka, were invited to the ICIAM23 Conference in Tokyo, Japan, where they had the chance to present their newest results in the minisymposium under the name “Recent Developments in Applied Inverse Problems”.
Both speakers would like to express their gratitude to the organizers Hiroshi Fujiwara and Kamran Sadiq for the invitation and the warm welcome in Tokyo.

We welcome a new member: Franziska Strasser

Dr Franziska Strasser

I recently completed my PhD in the field of optical tweezers with a focus on force and torque measurements, supervised by Monika Ritsch-Marte and Gregor Thalhammer. Now I am a postdoc in the SFB, in the subproject ‘Imaging of Trapped Particles’, where I work together with Mia Kvåle Løvmo and Simon Moser on phase measurements of acoustically trapped objects. Being part of the SFB project is a fantastic opportunity for me to collaborate with other researchers”.

We are honoured to have Franziska as part of our team and look forward to her contributions ahead.

Meet our newest member: Christian Wald

Dr Christian Wald

“I recently joined the applied mathematics group of Gabriele Steidl at TU Berlin. Currently, I’m working on modelling the movement of single molecules in an environment of molecule clusters. My work also covers the estimation of model parameters from simulated, as well as measured data. While we start with classical Gaussian mixture models, we will investigate machine learning techniques for analysing the movement data. I’m very happy to collaborate with the group of Gerhard Schütz, who have a lot of experience with the corresponding microscopy methods”.

Christian did his PhD in Mathematics at Humboldt-Universität zu Berlin on the topic of p-adic quantum groups. Thereafter, he joined the radiology group of Charite Universitätsmedizin Berlin, where conducted research on deep learning for cardiac CT and image reconstruction with unrolled neural networks for multi-coil radial MRI.

We feel privileged to welcome Christian into our SFB family and foresee great things ahead.
