The laser scanning microscope topographic picture shows a porous paper surface.

After gaining a Swiss professional certificate as a chemistry lab technician I gathered more than 15 years of experience in the fields of asbestos replacement, concrete, floculation chemistry, plastics and rubber development, pigment and paper chemistry. Currently I'm working as a research scientist with the world's leading producer of natural calcium carbonatDue to outstanding studies I was offered, in 1998, a post experience research studentship (part-time) at the University of Plymouth (UK) in the Department of Environmental Sciences . The initial MPhil research was upgraded to a direct PhD approach and completed in 2002. My research interests are liquid  wetting and spreading phenomena, transport into porous structures, especially related to paper printing applications, but also in relation to pharmacology, waste-water treatment and the manufacture of nano-composites. Furthermore I am interested in  visco-elastic interactions and rheological characterisation.

I conduct a research group of 10 scientists and assistants dealing also with product development and basic research for talc and calcium carbonates.

I have presented my work on many international conferences and published in more than 30 reviewed papers.(see below)

Regularyly I am invited for lectures at KTH University in Stockholm.
