About

New: DATA Analysis My scientific focus is on Mass Spectrometry; peptide & protein MS in areas like biotech (Proteomics & quantitative protein profiling, isobaric labelling, biomarker) and pharmaceutical industry (Antibodies, protein production, peptides and small molecules, GMP). I have preferences in science driven development of new ways of working - leaving well established limitations behind. Experienced in building a state of art MS Lab from the scratch. In Sanofi I lead a modern MS Lab and create knowledge and data to support the development of future biopharmaceuticals. "impossible" has a short lifetime - creativity together with team spirit across different disciplines enables to overcome well established limits and dogmas. (E.g. Tandem Mass tag, which allows today multiplexing of up to16 samples in one single run while delivering a relative quantitation for thousands of peptides in the samples. Such an innovation has enabled new applications.)
