Wouter Los initiated various developments in e-BioScience. He coordinated and participated in quite some European and international projects. The focus was mainly at environmental data services and data informatics, more specifically the establishment and development of environmental research infrastructures. He started initiatives for new research infrastructures at the national, European and global level. This resulted in a variety of activities resulting in currently established research infrastructures. Currently he is promoting the establishment of open data markets offering individuals, organisations, and governments, the mechanisms to control their own data, how they want to act in data sharing, and about collaborative opportunities. The EOSC is an example of a specific market sector in the developing ecosystem of open data markets.
