His research topics focus on solid mechanics, damage mechanics, micromechanics, multi-scale mechanics, computational mechanics with applications on advanced highstrength materials, metamaterials, materials for energy, health. He is also chairing the group’s multi-scale lab, which allows for quantitative in situ microscopic measurements during deformation and mechanical characterisation of a broad class of materials, structures, MEMS etc. on a wide range of length scales from nanometres to centimetres His research work serves the development of advanced engineering materials, additive manufacturing systems, MEMS & microsystems, materials for fusion, innovative metamaterials, etc.  Most activities are carried out in support of key Dutch and European industrial partners. Research grants to support the work have been obtained in a structural manner from ERC (Advanced Grant), NWO (former STW, FOM), EU, M2i (Materials Innovation institute) and industry. At present, research focuses on the science of additive manufacturing, novel models for complex interfaces, novel methods to unravel and design mechanical metamaterials, novel methods to bridge scales combined with reduced-order approaches, and multi-physics problems. His educational activities span all levels from BSc (e.g. solid mechanics), to MSc (e.g. continuum mechanics & nonlinear problems), to PhD (EM multi-scale and micromechanics; CISM courses). He supervised more than 50 PhD students, among which 14 are now faculty members in 11 different countries, whereas most other former PhD students started a successful career in industry.
