Lebenslauf

Stefanie Dencks studied electrical engineering at the University of Hanover, Germany, and continued her studies of biomedical engineering at the Technical University of Dresden, Germany. There, she received the Dipl.-Ing. degree in 2002 and also finished supplementary courses of Latin America studies including a stay abroad in Santiago, Chile, for her diploma thesis.

In 2003 she joined the Medical Physics group in the Diagnostic Radiology of the University Hospital in Kiel, Germany, where she worked on ultrasound characterization of bone and ultrasonic signal analysis within the EU-project FEMUS (development of an ultrasound scanner for the proximal femur) and the DFG-project “Multimodal ultrasound-based assessment of cortical bone strength”. (During this time she took two parental leaves.) In 2008 she got a scholarship of the Wilhelm and Günter Esser-Foundation, Bochum, to complete her research, and in 2009 she received her Dr.-Ing. degree in electrical engineering from the Ruhr-University Bochum, Germany.

From 2009 to 2011 she was member of the research staff of the Ultrasound Department of Physikalisch-Technische Bundesanstalt (national institute of metrology) in Braunschweig, Germany, where she did research on monitoring high-intensity focused ultrasound therapy. Since 2011 she is Senior Scientist at the institute for Medical Engineering at the Ruhr-University Bochum, Germany.

Her research is focused on medical ultrasound comprising signal analysis as well as imaging and image processing. Current applications are therapeutical ultrasound, quantification of ultrasound contrast media, and the enhancement of the visibility of cannulas in US monitoring.
