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.

Wanda Vossius (PhD student)

Wanda is working on the design of new fiber sensors to measure seismic noise with high precision at low frequencies dedicated as Newtonian Noise sensor network for the planned gravitational wave detector in Europe Einstein Telescope. She is investigating the properties of fiber Bragg gratings, mirrors, and oscillators introduced into the fiber, and how they accommodate different degrees of freedom of seismic signals.

Spiridon Beis (student assistant)

Spiridon is studying physics in Aachen. At HSU, he actively supports the WAVE project remotely as a student assistant by analysing data and monitoring the live streams on Twitch and social media. Spiridon is in the Einstein Telescope Collaboration, where he works on Newtonian Noise Cancellation and does simulations for sensor optimisation.

Max-Leopold Weilepp (soldier assistant + Bachelor student)

Max is soldier and is working on determining the scratch depth in glass panes to ensure the safety of tanks in the Bundeswehr and will be writing his bachelor’s thesis on possible measuring systems.

Julian Nathan Putz (soldier assistant + Bachelor student)

Julian is soldier and is involved in the HSU racing team. As an assistant, he works with Sebastian to create a new lab experiment for the metrology lecture. In his Bachelor’s thesis, he will characterize an APPS (Accelerator Pedal Positioning Sensor) from Formula Student for the electric racing car in the racing team and compare analog and digital approaches.

Sebastian Hamborg (soldier assistant + Bachelor student)

Sebastian is soldier and is involved in the HSU racing team. As an assistant, he works with Julian to create a new lab experiment for the metrology lecture. In his bachelor’s thesis, he will characterize and investigate the Break System Plausibility Device (BSPD) within the racing team according to the current Formula Student regulations. Sebastian is, therefore, examining the general functionality and reliability over a longer period of time, taking into account interference factors, and has also set himself the goal of working out possible improvements to the system.

Judith Nabel (team assistance)

Judith supports the metrology group with any kind of administration and organization.
