Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

On 7 May 2020, Jolanda van der Vliet defended her thesis 'The International Legal Protection of Environmental Refugees. A human rights-based, security and State responsibility approach'. The doctoral research was supervised by Prof. N.J. Schrijver and Prof. J.J.C. Voorhoeve.
