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.

Thirteenth Internal SFB Meeting

The 13th Internal SFB Meeting took place between 12-15 February in Villa Sonnwend, Roßleiten, Austria. It was an action-packed event featuring notable talks from members, as well as memorable debuts from external and international participants from realms as far flung as Finland.

In addition to the talks, there was a free afternoon on Tuesday 14 February which coincided with Valentine’s Day.

The newest addition to our team: Stefanie Reiter

The SFB team welcomes its newest member Stefanie Reiter to its ranks. Stefanie had previously completed her bachelor’s and master’s studies at the University of Vienna’s Department of Astrophysics where she had worked on studying dust dynamics in planetary systems.

“I am currently working as a PhD student at the Department of Astrophysics at the University of Vienna on the research project “Interdisciplinary Advances in Extragalactic Archaeology”, which works towards the aim of identifying specific events in the formation histories of nearby galaxies, using orbit-based dynamical modelling in combination with stellar population labels, as certain quantities are approximately conserved during a galaxy’s evolution. For this project, I am working on applying new uncertainty quantification methods for the models and including additional stellar population labels”.

Twelfth Internal SFB Meeting

The Twelfth Internal SFB Member Meeting took place between 4-7 December 2022 in the Obergurgl Universitätszentrum in Tyrol, Austria. Participants, both internal and external, were treated to a wealth of talks, both concerning progress within the various Tomography Across the Scales subprojects, and also from our external guests, who presented their related research.

Beyond the presentations and collaborative discussions, many members also took the opportunity to ski and hike, for which there were plentiful opportunities in the nearby vicinity.

SFB Members at the RICAM Special Semester – Workshop 5

The Special Semester on “Tomography Across the Scales” concluded with its final workshop on “Inverse Problems in Large Scales” and spanned the interval between 28 November – 2 December 2022.

Fabian Hinterer during his talk

There, SFB member Fabian Hinterer gave a talk on “a projected Nesterov-Kaczmarz approach to stellar population distribution reconstruction in Extragalactic Archaeology” in the presence of experts spanning the various mathematical branches that are connected to inverse problems. Other SFB members were also participants, including organisers Otmar Scherzer and Ronny Ramlau, as well as Peter Elbau, Michael Quellmalz, Ekaterina Sherina, Simon Hubmer and Kemal Raik.

We would once again like to thank the organisers for their hospitality and providing the platform for experts in the area to share and exchange ideas.

Kemal Raik is the new Scientific Project Coordinator

Dr Kemal Raik – Scientific Project Coordinator

The SFB team welcomes new team member Kemal Raik as its latest addition. He will function as the scientific project coordinator and will be responsible for organisational as well as administrative elements of the project. Kemal Raik, now at the University of Vienna’s Computational Science Centre, had previously been employed at the Industrial Mathematics Institute of the Johannes Kepler University Linz and brings with him his expertise on inverse problems and regularisation theory. We look forward to fruitful collaborations and working together with him.
