This Action will contribute to the sustainable development of European chemical industries in the coming decades by delivering an ambitious doctoral training programme that draws on expertise from industry and academia across 4 European countries. The research agenda and experiential training will grow the skills base beyond approaches that have relied upon a limited set of molecular scaffolds and a relatively small sub-set of reactions to exploit new reaction paradigms and platforms (e.g. high throughput experimentation, photoredox & electrochemistry) that meet the needs of modern drug discovery science.
