The final SFB internal meeting

From 2 to 5 December 2025, members and guests of the SFB Tomography across the scales met at the Obergurgl Centre in Tyrol, Austria. Researchers from pure and applied mathematics, physics, biology and medicine came together to discuss imaging and inverse problems related to tomography.

The inspiring mountain setting allowed for an enjoyable meeting with plenty of opportunities for intense scientific exchange and informal conversations. Alongside the PIs and the SFB members, we were glad to be joined by former SFB members as well as external international speakers. We look forward to the final SFB conference in Vienna – stay tuned!

Otmar gave a presentation at the AIP 2025 conference

Professor Otmar Scherzer, the speaker of the SFB project “Tomography across the scales”, presented a talk titled Regularization of Nonlinear Inverse Problems – From Functional Analysis to Data-Driven Approaches at the mini-symposium “Fortieth Anniversary of the Journal Inverse Problems” at the 12th AIP 2025. The biannual Applied Inverse Problems (AIP) conference is one of the biggest conferences in its field. This year, it was held in Rio de Janeiro, Brazil, from 28 July to 1 August.

Seeing Inside: Exploring Computed Tomography with Kids

This year, Axel Kittenberger, Denise Schmutz, and Noemi Naujoks once again participated in the Vienna Children’s University, this time with two workshops, each tailored for 20 children aged 7 to 9. Building on last year’s popular topic, we brought back Paula the Sloth to help explain the fascinating world of computed tomography in a playful and accessible way.

The children explored the fundamentals of tomography through a series of interactive stations. These included quizzes, experiments with light and shadow, paint-by-numbers, and exercises demonstrating how mathematics enables us to visualize the inside of objects.

We were excited to see how quickly the children understood complex ideas when given the chance to explore them in a fun way.

PhD Defense: Shiyu Deng

We are pleased to announce that Shiyu Deng, a former PhD student in the subproject Multi-Modal Imaging, successfully defended her PhD thesis with the title “Technical Advances in Dual-Modal Preclinical Optical Coherence and Photoacoustic Microscopy” on 25 June 2025.

Shiyu’s doctoral studies were supervised by Prof. Wolfgang Drexler, Head of the Center for Medical Physics and Biomedical Engineering (Medical University of Vienna), and co-supervised by Prof. Leopold Schmetterer (Nanyang Technological University). Congratulations Shiyu from the SFB team! We wish you all the best for your future.

SFB Conference “Tomography across the scales”


The SFB Conference “Tomography across the scales” took place from the 16th to the 20th of June at the beautiful Lake Wolfgangsee venue close to Strobl.


We were delighted to welcome many distinguished speakers from renowned international universities. The meeting provided a valuable opportunity to foster interdisciplinary communication and facilitate networking between tomography experts from various disciplines, including astronomy, inverse problems, medicine, biology, and physics.

During the free afternoon, some participants took part in an excursion to the lake Schwarzensee, where they enjoyed the breeze and the view of the lake, while others took the cog railway up Schafberg to enjoy the panorama.

SFB Member Mia Kvåle Løvmo interviewed by Innovation Tirol

We are pleased to announce that our SFB member, Mia Kvåle Løvmo, Postdoctoral Researcher at the Institute for Biomedical Physics at the University of Innsbruck, was interviewed by the magazine top.tirol in the Innovation Tirol section. The interview focuses on Mia’s research into a technology that utilizes ultrasound to move organoids in a controlled manner, without mechanical confinement, enabling the phenomenon known as “acoustic levitation.” The full interview (in German) can be found at: https://www.top.tirol/news-forschung-innovation/forschung-in-der-schwebe.
