I hold a doctorate in chemistry, specialising in organic chemistry, and a diploma in environmental engineering. For more than 25 years, I have worked on the assessment of hazardous substances, biocides and chemical products and on options for their substitution.
My professional career began in technical planning offices. There I was involved in sampling, analysis and assessment of sewage treatment plants.
From 2000 to 2012 I worked at the Interuniversity Research Center for Technology, Work and Culture (IFZ) in Graz and temporarily headed the “Ecological Product Policy” research area. My work focused on the assessment of hazardous substances in disinfectants and cleaning agents, cosmetics and nanoproducts.
The WIDES disinfectant database emerged from the work on disinfectants. The City of Vienna makes this evaluation and information system publicly available to procurement managers, hygiene specialists and other interested parties.
I have been self-employed with the Technisches Büro Klade since 2012. A focus of my work is the technical support and further development of the WIDES database. I also prepare studies and comparative assessments on the use of biocides – including in evaporative cooling systems, façade coatings, household products and rodenticides.
