We are a team of scientists working at the frontier of organic chemistry to other disciplines like biological chemistry and structural biology. We focus on the implementation of small molecules as tools to study complex biological systems. In our current projects, we design 13C, 15N and 2H labeled metabolic amino acid precursor compounds, which can be used in cell-based protein overexpression. The target proteins show distinguished isotope patterns and represent valuable probes for biomolecular NMR experiments. Learn more about our research, see some structures of our labeled precursor compounds or read through our list of publications. If you need further information or want to collaborate on an interesting research topic don't hesitate to write to roman.lichtenecker@univie.ac.at.

 Moreover, we are very active in teaching different aspects of chemistry at the University of Vienna with currently 5 lectures and 2 seminars per year.  We additionally offer courses for advanced chemistry students within the context of our research projects.
