SFB at Acoustofluidics conferences in Uppsala and Cargèse

Acoustofluidics 2024 conference in Uppsala.

This fall, two members of our SFB team, Monika Ritsch-Marte and Mia Kvåle Løvmo from the subproject on imaging of trapped particles, had the opportunity to attend two prominent international conferences focused on acoustofluidics.

The annual Acoustofluidics 2024 conference, organized by the Acoustofluidics Society, took place in Uppsala, Sweden, from August 14 to 16.

Researchers from around the globe gathered to share insights and discuss a diverse range of topics related to acoustic trapping and microfluidics – from theoretical advancements to innovative devices and novel applications.

In September, The European Summer School on Physical Acoustics and its applications was held in Cargèse in Corsica. The summer school offered a week filled with courses on ultrasonic fundamentals and engaging ‘Hot Topic’ seminars led by experts in the field. Attendees benefited from experimental demonstrations and numerical tutorials that provided valuable hands-on experience, and young researchers also showcased their work through short talks and poster sessions.

Monika was an invited keynote speaker in Uppsala. In Cargèse, she teamed up with Bruce Drinkwater, and together, they gave a ‘Hot Topic’ seminar on the ‘Parallels, Differences and Synergies of Optical and Acoustic Manipulation’. Mia contributed presentations on her recent work on acoustofluidic devices for optical tomography.

Both Uppsala and Corsica events offered great opportunities for sharing knowledge, fostering collaborations, and discussing the latest advances in acoustic manipulation – in peaceful and beautiful surroundings.

16th SFB Internal Meeting in Strobl

From 1 to 5 July, the 16th SFB internal meeting took place at a beautiful venue of Lake Wolfgangsee in Strobl. This annual summer meeting offers SFB members a valuable opportunity to share recent progress in the eight different projects and discuss future research directions. We were honored to host three internationally renowned professors as invited speakers – Markus Grasmair, John Schotland, and Ivo Ihrke – as well as early-career researchers Andrea Aspri and Alina Boecker. Researchers and PhD students from Austrian institutions of excellence (RICAM, University of Vienna) and Germany also participated in the meeting.

During the event, we celebrated the 60th birthday of the SFB Speaker, Professor Otmar Scherzer.

Professor Otmar Scherzer is an internationally recognized mathematician known for his work in applied mathematics, particularly in the fields of inverse problems, imaging, and numerical analysis. He has received numerous awards, including the Förderungspreis of the Austrian Mathematical Society in 1998 and the START-Prize from the Austria Science Fund (FWF). He will also be an invited speaker at the Applied Inverse Problems (AIP) Conference in Brazil in 2025.

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.

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.
