Junior-Professorin Dr. rer. nat. Katharina-Sophie Isleif

Katharina is a physicist and junior professor of metrology at HSU. In her research group she investigates optical laser interferometers and sensors for measuring gravitational waves, seismic waves and much more. The goal is to find smart and compact interferometer solutions for various applications. For this, they are researching and developing alternative interferometer techniques, such as digital interferometry. You can find her different research projects here.

Sangmin An (PhD student)

Sangmin works on a dtec project and designs new optical interferometer concepts. He investigates new optical designs using IfoCAD software and then tests them in the laser lab on the HSU campus. The goal is to develop wireless, stand-alone optical sensor with high precision and at the same time high robustness (high dynamic range).

Lars Bretthauer (PhD student)

In collaboration with the department for electrical engineering, Lars works on the dtec project “Digital Sensor-2-Cloud Campus-Plattform” on sensor networks and the signal processing interface to realize a wireless sensor network. He is currently using MEMS sensors for this purpose and is also investigating alternative techniques to improve the positioning between two MEMS sensors.

Reinhardt Rading (PhD student)

Reinhardt works on seismic fiber sensors with the WAVE team at the Bahrenfeld research campus and develops new broadband fiber sensors with digital laser interferometry in the laboratory. He is also working on simulations for optimal sensor positioning to suppress noise (e.g. Newtonian noise in the planned gravitational wave detector the Einstein Telescope).

You can find more information about Reinhardt here.

Julian Dietz (Master student)

Julian is a soldier and mechanical engineering student and started his master thesis in the metrology group in March. He is working on distributed acoustic sensing (DAS) and is currently investigating how to best couple the fiber to its environment. Julian is conducting the measurements at the Bahrenfeld research campus in cooperation with the WAVE team.
