At the Materials and Mechanics Lab in Stony Brook University, we are interested in studying the mechanical and failure behavior of materials. We consider a variety of loading and environmental conditions with the problem space spanning a wide range of length and time scales.

We are interested in a wide range of materials, such as fiber reinforced composites, polymers and their nanocomposites, soft materials, and 3D printed materials. We employ a combination of numerical, experimental and theoretical approaches.

We strive to develop new and improved computational and analytical models, and experimental methods. The ultimate goal is to enable safer, reliable and efficient designs of components and structures in various engineering applications.
