This GRAL project is very, very good, the work done is excellent and I strongly recommend it for continuation and full support. They have made very good achievements on both research axes and have been able to coordinate the efforts of several scientists expert in different and quite divergent domains. I doubt they could have gone so far without the help of LabEx. In particular it is worth of note to see that, thanks to strong ties with industries, they were able to collect funds almost matching those granted by LabEx, namely a grand total of 5.341.000 Euros, a non negligible amount. I also think that their teaching and training of both PhD students and Post Docs is well above average and should bring long-term results permitting to their PhD graduates to obtain good jobs and positions both in industry and universities. In summary, I believe that the grant invested in this proposal has been well spent, the results obtained so far have been outstanding and well in line with their proposal and thus I strongly recommend continuation.
