The long-term research goal of my group is to gain fundamental insight into the mechanics and dynamics of biological and bioinspired systems at multiple-length scales, and reflect knowledge gained from these studies to the development of bioinspired design principles. Our investigations begin typically at the nano-scale, where key chemical information is encoded in the basic building blocks and interfaces of materials, giving rise to emergent features observable at the macro-scale. The main focus of our work is establishing "materials-by-design" approaches to understanding the mechanics of polymers, biomolecules and nanomaterials, as well as their interfaces, to achieve new capabilities in engineering systems. We build and utilize a broad set of tools based on theoretical mechanics and computational materials science, most notably atomistically informed coarse-grained molecular dynamics simulations to tackle challenges pertaining to modeling phenomena spanning multiple length and time scales. One of our core interests is to create physics-based approaches to quantitatively and predictively simulate materials behavior at multiple scales. The majority of our work focuses on understanding how size and geometric effects influence the mechanics of confined solids and fluids at the nano-scale. Discovery of size-dependent phenomena that may facilitate advancements in the design of functional nanostructures, structural/infrastructural materials, and nanotechnology products is central to our long-term research objective. The fundamental scientific advances in materials-by-design and bioinspiration are aimed at tackling two major interdisciplinary materials challenges relevant to civil and environmental engineering: 1) making materials stronger, lighter, tougher and cheaper by nanostructuring, 2) addressing clean water and carbon capture needs through novel membranes.
