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.

Science Meets Kids: The Fascinating World of Computed Tomography

During the 22nd Vienna Children’s University, young students aged 7 to 12 had the opportunity to dive into the fascinating world of computed tomography. Noemi Naujoks, Axel Kittenberger and Denise Schmutz gave an engaging lecture featuring Paula the Sloth as a fun and relatable example for the children.

The lecture was held twice to accommodate the interest, with around 180 children attending both sessions. The interactive format provided the children with not only theoretical knowledge but also practical experiences. Through experiments, a quiz, and special math exercises, the children learned how computed tomography works and the role mathematics plays in it.

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.

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.
