Current
My topics in the last years of my career are mainly centered around engineering ethics as a field of applied ethics. In addition, I try to establish many transdisciplinary interactions with areas of technology that could be of reflective interest to an engineer. (see ethics essays)
VCI project Ethics in Chemistry 2024-2027
The aim of the project is to create an external learning platform on the topic of pharmaceutical ethics.
From 2000 -2018
I was passionate about applied non-classical chemistry. This refers to the initiation of chemical reactions through non-thermal activation. This can involve activation by sound waves, light waves, especially sunlight, or mechanical shocks.
In my research, the application of these non-classical processes mostly focuses on the degradation of anthropogenic pollutants/trace substances from water cycles or the solvent-free synthesis of active substances.
Photocatalysis
AIF project Sonochemistry 2002-2004
The aim of this project was to investigate the mechanism of the sonolytic chemical degradation of diclofenac in water. We investigated the oxidative degradation of this anti-inflammatory drug as a function of sound intensity, sound frequency and the addition of catalytic particles.

DBU project: Photocatalysis process for the removal of pharmaceutical residues 2004-2007
Pharmaceutical residues pose a potential risk to aquatic organisms in water cycles. At higher concentrations in flowing waters, there is also a risk of contamination of drinking water due to accumulation. Using newly developed carrier catalysts made of natural ceramic granules and UV light, energy-efficient degradation is possible.

BMBF joint project NanoPharm 2010-2014
Various collaborative partners investigated ways to realize the degradation of active pharmaceutical ingredients in water using nanoscale catalysts and UV light or natural sunlight. Various reactor concepts were pursued and compared with each other. Solar catalytic granules through simple production were the focus of interest.
