Two newly appointed professors start in August

portaits of Ralf Hielscher und Daniel Hiller
With immediate effect, Professors Ralf Hielscher and Daniel Hiller occupy the professorship for Analytical Methods of Signal and Image Processing (Faculty 1) and the Heisenberg Professorship "Physics of Quantum Materials" (Faculty 2).

With Prof. Ralf Hielscher, a former Freiberg doctoral student, is returning to the TU Bergakademie Freiberg after stays at the Lomonossov University Moscow, the Helmholtz Center Munich and the TU Chemnitz. In the field of applied analysis, the mathematician deals with problems of numerical harmonic analysis and approximation theory. "Reconstructing relationships based on as little data as possible is one of the key mathematical questions in the research field of artificial intelligence," says Prof. Ralf Hielscher.

Within this area, he is primarily interested in data in curved spaces, so-called manifolds, such as those found in geology or robotics, for example. As a mathematician, it is particularly important to him to make the methods he has developed accessible to a wide range of users. This is illustrated by the MTEX software developed under his leadership, which has been used internationally for the analysis of polycrystalline materials for 15 years.

Prof. Ralf Hielscher sees the strong expertise of the TU Bergakademie Freiberg in materials science, crystal physics, geology and mineralogy as an ideal starting position to apply his mathematical know-how in an interdisciplinary manner. "New measurement methods always require new methods of signal and image processing in order to get the most out of the data," says Prof. Ralf Hielscher. "I am looking forward to getting to know the TU Bergakademie Freiberg in all its breadth and to supporting its profiling through my research."

Heisenberg professorship for Daniel Hiller

Equipped with a Heisenberg professorship from the German Research Foundation (DFG), Prof. Daniel Hiller started his work at the Institute for Applied Physics. DFG funding is set up for up to five years and supports the establishment of the professorship in the first few years. The qualified physicist is an expert in nanoelectronics. In addition to research and teaching activities as a Feodor Lynen Return Fellow of the Alexander von Humboldt Foundation at the TU Dresden and the Helmholtz Center Dresden-Rossendorf, he had several research stays in Europe and Australia. He deals with new methods of doping nanostructures and investigates special interface defects for applications in nano and quantum electronics. At the end of 2019, Daniel Hiller was accepted into the renowned Heisenberg program of the DFG.

At the TU Bergakademie Freiberg, the physicist would like to use novel physical and quantum chemical effects to control the conductivity of nanowire transistors and thus enable even smaller, more powerful, and, above all, more energy-efficient components. “The miniaturization of transistors on chips is reaching more and more fundamental limits, so that new research approaches are necessary for further development. I look forward to being able to carry out this exciting research work at the Institute for Applied Physics in cooperation with the central cleanroom laboratory of the TU Bergakademie Freiberg, "says Prof. Daniel Hiller.
With the Heisenberg professorship, the new research area physics of quantum materials in the field of silicon and germanium semiconductors at the TU Bergakademie Freiberg is to be established.
