Joao Marreiros will join the group on August 1, 2015. Joao is originally from Portugal and knows about aerospace engineering as well as chemistry. In our group, he will investigate building block mobility and defect creation in metal-organic frameworks, supported by MSCA-ETN project DEFNET. The research and training in DEFNET are structured into 8 work packages (research, training, outreach, management) which will provide the ESRs with a fundamental knowledge and excellent education in the most exciting and emerging field of molecular framework materials science (MOFs). Welcome Joao!
