Professional development

Between 1992 and 1997 I studied mining, with emphasis on beneficiation, at the RWTH Aachen. Since I enjoy dealing with resources, I did my doctorate at the department for beneficiation and recycling of solid wastes at the RWTH Aachen.

In the context of my doctorate I contributed to the development of a new guideline on solid waste sampling (LAGA Guideline PN 98) at the DIN e.V..

In 2002, after finishing my doctorate, I obtained the Lise-Meitner scholarship (of the federal state of North Rhine-Westphalia), which allowed me to work at the ‘Natural Resources Canada’ Institute in Ottawa (Canada) for two years. During my stay at the Institute I realized a study on the environmental impacts of recycling technologies for used tires.

After successfully acquiring and working on a research project dealing with energy efficient feed production at the University of Bremen (Institute for Integrated Product Development), I changed to COAST at the University of Oldenburg in 2012. 

At COAST I lead the projects HEC and Groen Gas. Besides, i am regularly assisting the Ingenieurinnen Sommeruni (female engineers summer school) as lecturer at the University of Bremen.
