On my own behalf

At the moment I am looking for opportunities for cooperation or further education in the field of NMR of peptides. The focus is on spectra interpretation and structure generation. Although I have more than 30 years experience in NMR, I have been working in the field of small molecules.
For my privately operated chemistry pages I am also looking for possibilities of cooperation in order to expand my content.
