The course is aimed at PhD students and post-doctoral researchers on the first years after obtaining their degree (with provisions for career breaks) who would like to learn more about the basic theory and applications, along with the various steps from sample preparation, data acquisition and processing to outcome analysis on MX, NMR, MRMS and EM technologies. Furthermore, the participants will become acquainted with the technology catalogues provided by Instruct-ERIC and iNEXT-Discovery, thus boosting a bottom-up-approach to apply for access to these EU centers and facilities.
