# Angkana Rüland: New Hausdorff Chair at the HCM

**Bonn, 10.02.2023. Angkana Rüland has accepted the offer of a Hausdorff Chair. These are professorships for outstanding scientists at the Hausdorff Center for Mathematics (HCM). The 35-year-old, who is herself an alumna of the University of Bonn, is the second woman to hold this position. She will take up her professorship in March.**

Angkana Rüland's research is strongly inspired by problems that arise from the natural sciences and lead to exciting mathematical questions and structures. One example from materials science is the precise analysis of so-called shape memory alloys - special metal alloys that have a "memory" due to their thermodynamic behavior and can seemingly "remember" a previous shape despite severe deformation. "Modeling these materials and analyzing the associated microstructures leads to problems that are fascinating both from an experimental, application-oriented point of view and from an inner-mathematical point of view," says Angkana Rüland.

Another subject of her research are so-called inverse problems, in which one wants to obtain the most accurate information possible about objects through indirect, non-invasive measurements - as is the case, for example, in X-ray tomography. Another example of such an inverse problem are "indirect" navigation systems of animals, bats and dolphins for example.

#### Commitment to research and teaching

Angkana Rüland brings a team of two doctoral and postdoctoral researchers to the university. "The mathematical environment in Bonn is an internationally outstanding place to work in mathematics in general and in analysis in particular - both in research and in teaching," she says. She is looking forward to an extremely strong and diverse group working in pure and applied analysis. "With a huge range of research seminars, colloquia, international workshops, summer schools and conferences, and exceptionally motivated and talented students, it's a tremendous opportunity to work in such an inspiring atmosphere."

Angkana Rüland is particularly interested in promoting young talent and, in particular, in the exchange with students. Already in her student days, she was one of the first members of the HCM "school team". There, committed mathematics students strive to make university mathematics comprehensible to school children. In addition, Angkana Rüland was part of the founding team of the Bonn Math Club for children in school grades seven to ten.

#### Close relationship with Bonn

Angkana Rüland has a close connection to Bonn. She went to school here and she began studying mathematics while still at high school as part of the early study program "FFF - Fördern, Fordern, Forschen" at the University of Bonn. After graduating from high school, she continued her studies at the University of Bonn. In 2014, she completed her doctorate under Herbert Koch at the Mathematical Institute and received the "Hausdorff Memorial Prize" for the best dissertation in mathematics in Bonn.

After her PhD, she went to the University of Oxford as a postdoctoral researcher and subsequently became a junior research group leader at the Max Planck Institute for Mathematics in the Sciences in Leipzig in 2017. In 2020, Angkana Rüland received an appointment at the University of Heidelberg as a W3-professor. Now she returns to Bonn and joins the excellent circle of top researchers at the Hausdorff Center for Mathematics as the second female holder of a Hausdorff Chair after Ana Caraiani.

#### Angkana Rüland at the Math Night

Anyone interested can learn more about Angkana Rüland's research at the seventh "Math Night", which the Hausdorff Center for Mathematics is hosting as an online event on March 14 - this year in collaboration with the Leipzig Max Planck Institute for Mathematics in the Sciences. Her talk will be held in German.
