Mass Spectrometry & Protein Chemistry

Karl Mechtler (Head)


Mass spectrometry (MS) has emerged as a core analytical technique in protein chemistry

Driven by the rapid development of instrumentation, analysis methods and computing tools, MS based proteomics is at the forefront of techniques in modern life science research. 

In the Mechtler lab, we are interested in developing new methods to increase the sensitivity, accuracy and precision of protein identification/quantification and the detection of post translational modifications. Our aim is to use these optimized methods to answer fundamental biological questions.
