Dr. Hendig received her Ph.D. in biochemistry from the Bielefeld University, Germany, in 2008. She is currently working as postdoctoral research fellow at the Institute of Laboratory and Transfusion Medicine of the Heart and Diabetes Center North Rhine-Westphalia in Bad Oeynhausen, Germany.

Scientific research at the institute is mainly concerned with the pathobiochemistry of extracellular matrix, the molecular diagnostics and cellular pathophysiology of pseudoxanthoma elasticum and the development of molecular biological methods for the detection of bacteria and viruses relevant to transfusion and infection. The PXE research group in Bad Oeynhausen is analyzing PXE-causing sequence variations in the ABCC6 gene. Further projects on PXE include elucidation of the cellular pathophysiology of extracellular matrix alterations in PXE. Additional foci are the identification of secondary genetic risk factors and evaluation of biomarkers which are suitable for determination of disease status and progression.

Dr. Hendig´s major research interests are the pathogenesis of extracellular matrix perturbations leading to human disease. Injuries of extracellular matrix structures lead to an unregulated activation of synthesis and degradation of matrix proteins and finally result in currently untreatable fibrosis and extraosseous calcification. Therein, her primary research focuses on proteoglycans, which represent sugar-containing proteins and the key enzymes involved in their synthesis. Dr. Hendig´s other research topic deals with the regulation of biological calcification in connective tissues.

The results of Dr. Hendig´s work on PXE were distinguished by the American Association of Clinical Chemistry and the Vereinigung südwestdeutscher Dermatologen in 2005. Her research on PXE was funded by grants from the Foundation for Pathobiochemistry and Molecular Diagnostic of the German Society for Clinical Chemistry and Laboratory Medicine (2005-2007) from the Ruhr-Universität Bochum, Rectorate Program (2009-2011) and from the Deutsche Forschungsgemeinschaft (DFG, since 2010).
