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.

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.

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.

SFB Member Meeting in Gmunden

From 26th to 29th of September 2022, the SFB members and project associates met in person for the Fifth SFB Member Meeting, which took place at the “Hois’n Wirt” Hotel in Gmunden. This was the first member meeting held in the second funding period of the SFB project and also the first one after covid-19 restrictions. All participants had a chance to present and discuss their work and broader research interests related to their sub-projects in a casual atmosphere. The members enjoyed the enlightening variety of topics reflected in the event program, fruitful interdisciplinary collaboration discussions and a hike up Grünberg and Laudachsee.

A big thanks to all members for their active participation and also to the member speaker Ekaterina Sherina for organizing this event!
