The High Performance Materials and Structures Lab

Our group is focused on studying the mechanical behavior and performance of materials and structures, at various scales from nanowires and living cells to ships and buildings. Our special interest and expertise is development of new concepts and designs for enhancing the performance of structures and materials. We use a combination of methods that range from simple observations and simple scaling laws to detailed computational models and sophisticated experimental equipments to carry out our work.

Topics of our work are generally motivated by considering the current challenges and needs in structures, mechanics, materials including biomaterials and biomechanics and nanotechnology. Many of these topics are initiated and carried out via our industrial collaborations.
