Subject to the successful signing of the EU Grant Agreement, a call for 17 DC (Doctoral Candidate) positions is open within the context of the Doctoral Network (DN) project MC4DD.
The Doctoral Network MC4DD "MC4DD – Macrocycles for Drug Discovery", funded within the framework of the Marie Skłodowska-Curie Actions (MSCA), follows an interdisciplinary and cross-sectoral approach by bringing together leading experts in macrocyclic drug discovery from academia and industry from the fields of organic synthesis, medicinal, high-throughput and computational chemistry, pharmacological and structural analytics, and modelling.
Eight academic research groups and five industrial partners, coordinated by Technische Universität Darmstadt in Germany, join forces in MC4DD to create a mobility and training platform for young scientists by means of cross-site, interdisciplinary research projects. The DCs will work on individual research projects to expand the opportunities of macrocycles as next-generation drug modalities.
What we offer
The project offers research and training excellence in medicinal chemistry and drug discovery. The partners of MC4DD are leading research groups in this field and their research institutes actively promote young researchers. The 8 academic research groups and 5 industry partners join forces in MC4DD to create a platform of intersectoral and multidisciplinary mobility and training.
To complement the academic and scientific goals of the DCs, the project offers customized research projects, structured interdisciplinary local and network-wide transferable skills training activities, and secondments at top-ranking European universities and industry partners.
