09/2024: Our 5th CRC 1456 Retreat in Hofgeismar
The annual meeting of CRC 1456 took place from 17 to 19 September. The program included three days of talks on the latest results of the subprojects, discussions and poster presentations. Ideas and experiences were exchanged between presentations. Canoeing together further promoted to get to know each other, to communicate and to collaborate.
It was a successful meeting for the more than 50 participants. We thank all of them for their participation, their commitment and their excellent contributions.

the “CRC 1456 Spring School 2024 on Novel Imaging Techniques with Waves” from March 11 to 14, 2024. Motivated by applications studied in CRC 1456, ranging from helioseismology to electron microscopy, this spring school focuses on modeling of new types of wave data, corresponding forward problems, and novel inversion techniques. They welcomed five speakers Shari Moskow (Drexel University, USA), Shari Moskow (Drexel University, USA), Vanja Nikolić (Radboud University, NED), Damien Fournier, (MPI for Solar System Research Göttingen, GER), Christoph Lehrenfeld (University of Göttingen, GER) and more than 30 participants to this event.

11/2023: Our 4th CRC 1456 Retreat in Hofgeismar
The CRC organised a 3-day retreat (November 13-15) at the Evangelische Tagungsstätte Hofgeismar

in the magical Reinhardswald. Our PhD students and some postdocs came together to discuss their research in a relaxed atmosphere. Each session started with mini-tutorials on specific research areas, followed by short presentations of current projects. This time we had a different approach to presenting everyone's work: the participants were teamed up and one had to present the slides of the partner, in order to broaden the understanding of everyone's work in our diverse and interdisciplinary CRC. We thank all participants for their commitment and contribution to this event.

09/2023: 11th Applied Inverse Problems Conference
From September 4-8, the CRC 1456 hosted together with the GRK 2088 and the IPIA the 11th conference of the series "Applied Inverse Problems" with more than 550 participants.

The AIP conferences are organized biannually and have become the largest conference series in the field. This year, there were more than 500 oral and 25 poster presentations from international scientists. The topics ranged from inverse problems in partial differential equations and regularization theory to themes like uncertainty quantification and machine learning, covering imaging techniques in astrophysics, geophysics, radiology, histology, and solid-state physics, to name just a few, but also applications in fields like econometrics, nuclear power safety, and many others. Fore more details visit here.

12/2022: Award for maths research
Dr Gilles Mordant (member of project A04) awarded annual prize by Royal Academy of Science, Letters and Fine Arts of Belgium.
He has been conducting research for one year in the Göttingen Collaborative Research Center SFB 1456 "Mathematics of Experiment" in the group of Prof. Dr. Axel Munk at the Faculty of Mathematics on statistical data analysis methods using the theory of optimal transport. "Building on my work in Belgium, I am developing new methods in Göttingen that help us understand the spatially complicated arrangement of elementary building blocks of the cell and their interaction. Göttingen offers a unique environment for me to work on the whole spectrum of the problem," Mordant said. For more details go to: "University of Göttingen - New press releases“. The CRC 1456 congratulates him!

09/2022: New Project A06 (Sinz/Gail)
The CRC 1456 welcomes Fabian Sinz and Alexander Gail as new principal investigators. They will start the project A06 "Predictive models and frame of reference in macaque sensorimotor cortex under natural conditions" in January 2023. The aim of this project is to develop graph based models for neural activity of freely behaving monkeys to better understand how the brain represent objects in space under natural conditions. The CRC 1456 congratulates both.
