Biography

After finishing a professional training as chemical-technical assistant and doing my military service I started my studies in Chemistry at the University of Hamburg in 2003. Based on contacts made during an ERASMUS exchange I did my PhD thesis at the Universities of Hamburg and Antwerp from 2008-2013. Topic of my Thesis was the development of scanning macro-XRF for the investigation of historical paintings, involving the design of instruments and development of data evaluation workflows.

I worked from 2013-2015 at the German Particle Accelerator (Deutsches Elektronen Synchrotron, DESY) in Hamburg at the hard X-ray micro-probe P06. Here I supported users in the investigation of microscopic samples with X-rays and explored the use of matrix factorization for spectroscopic imaging.

From 2015 to 2018 I was Junior Chair at the Laboratory for Molecular and Structural Archaeology (Laboratoire d’Archéologie Moléculaire et Structurale (LAMS)) at the Sorbonne University in Paris. Here I used X-rays and hyperspectral imaging to study remnants of paint on archaeological objects from Antiquity and Ancient Egypt.

After an intermediate stay at DESY, filling in my old position, I am since November 2018 Assistant Professor at the TU Delft for "X-rays in Art and Archaeology", working on the investigation of cultural heritage objects, the development of new data evaluation workflows and contributing to the Smart*Light project.
