Research interests:

  • Development of advanced computational modeling methods for designing new materials of advanced material functions.
  • Bottom-up modeling of the multi-scale structure-mechanics relationship of nano- and bio-materials. Fundamental understanding of the material behaviors of biological and synthetic polymeric materials from the most molecular scale to macroscopic length scale.
  • Learn from nature and discover bio-inspired ideas to create and design materials with innovative material functions.
  • Prototyping, optimization and characterization of synthetic composite materials with multiple advanced material functions, for efficient usage of engineering materials.

Current Research:

My research focuses on developing advanced computational modeling methods, using them to study fundamental mechanical properties of biological materials and applying the knowledge to design new materials of advanced mechanical functions. I have a broad background in mechanics and structure of materials, with specific training and expertise in the multi-scale structure-mechanics relationship in biological materials. My research focuses on the structure and mechanics insight of general natural materials as many of them, such as mussel glue, insect wings and membranes, have fascinating mechanical and biological properties built up from simple basic molecular building blocks. I am thus strongly motivated to develop tools that enable us to learn from nature to make material innovations more efficient. I have developed a multi-scale high-throughput computational modeling method that enables me to study materials from the most fundamental molecular scale to macroscopic length scale. I have applied the tool to the investigations of several different biological materials and have revealed new mechanisms hidden in their complex structures. Some of the findings contribute to fundamental understandings of diseases that take place from the molecular scale; others contribute to designs and prototyping of synthetic composite materials with multiple advanced material functions. I have developed principles to help to optimize the material functions through structures, making it feasible to rationally design the mechanics and longevity of composite materials, leading to better performance with less energetic and environmental cost than conventional engineering materials for industrial applications.
