The world needs new multi-materials that are mechanically strong and tough in the practical continuum framework. These materials must be sustainable - even programmable to become compostable. These materials are researched via synthesis, experimental characterization, and numerical simulation. I target to progress the research of load carrying composite materials, focusing on i) scalability of thermo-mechanical features from micro to macro length scales, and ii) fracture, environmental degradation, thermo-mechanical deformation, and the durability of any bio-organism response. I love multi-disciplinary studies that combine various characterization methods, quantitative experiments, and numerical modelling.
