Wageningen University

The mission of Wageningen UR (University & Research centre) is ‘To explore the potential of nature to improve the quality of life’. Within Wageningen UR, nine research institutes – both specialised and applied – have joined forces with Wageningen University to help answer the most important questions in the domain of healthy food and living environment. With approximately 30 locations (in the Netherlands, Brazil, Chile, Ethiopia and China), 6,000 members of staff and 9,000 students, Wageningen UR is one of the leading organisations in its domain worldwide. The integral approach to problems and the cooperation between the exact sciences and the technological and social disciplines are at the heart of the Wageningen Approach.



 The Netherlands Institute of Ecology (NIOO-KNAW) 

NIOO investigates how nature works, across the globe. With more than 200 staff and students of about 25 nationalities, it is one of the largest institutes of the Royal Netherlands Academy of Arts and Sciences (KNAW). The institute’s research covers a wide range of subjects, including the function of biodiversity, animal personalities, toxic cyanobacteria, and antibiotic production by soil microbes. NIOO’s knowledge can help to address ecological and environmental problems caused by climate change, biological invasions, and  changing land use.


 The International Society for Microbial Ecology (ISME) 

ISME is the principle non-profit scientific society for the burgeoning field of Microbial Ecolgy and its related disciplines. ISME fosters the exchange of the scientific information by organizing international symposia as well as specific workshops, sponsoring publications, and promoting education/research. ISME provides services to the scientific as well as the wider community.


Koninklijke Nederlandse Akademie van Wetenschappen (KNAW)

The KNAW (Royal Netherlands Academy of Arts and Sciences), as the conscience and voice of arts and sciences in the Netherlands, promotes quality in science and scholarship and strives to ensure that Dutch scholars and scientists contribute to cultural, social and economic progress. As a research organisation, the Academy is responsible for a group of outstanding national research institutes. It promotes innovation and knowledge valorisation within these institutes and encourages them to cooperate with one another and with university research groups.
