Research summaryMass spectrometry-based proteomics and protein analysis

Research

My research interests are mostly in mass spectrometry-based protein analysis and proteome research on various biological systems. At present my main function is the management of the Centre for Protein Research.

Therefore my major focus is on method establishment and method development rather than on individual research projects.

However I am involved in various research projects in the field of mass spectrometry-based proteome/protein research and new collaborations are emerging at present which will result in more definable projects and research interests in the future.
