Welcome to my homepage!
I have great research interests in computational science and engineering, with an emphasis on multiscale modeling of the deformation and failure of complex materials, such as composites, granular materials, geomaterials, nanomaterials, biological materials, etc. My research aims to advance the understanding of macroscopic behaviors of these materials from their microscopic attributes, and to enhance predictive capabilities of robust computational models for applications in areas of aerospace engineering, defense, geotechnical engineering and energy production.
During my Ph.D. study at Columbia University, I focused on the multiscale modeling of granular materials. The objective was to develop efficient and robust multiscale models that bridge the length and time scales to better understand and predict granular material behaviors from discrete (the pore/grain-scale) to continuum (the field-scale) level. My doctoral research also concentrated on solving inverse problems in geosciences. For example, I proposed a staggered multilevel approach to identify material parameters for macroscopic phenomenological model with limited or insufficient available experimental data through establishing a so-called Extended Digital Database. I have also been working on the development of regularized phenomenological multiscale model to study brittle failure of composite materials, parametric modeling of unit cells with versatile microstructure morphological details, developing singlescale and multiscale models of polyurea and high-density polyethylene (HDPE), and simulation of fragment simulating projectile impacting polyurea/high-hard bi-layers at high impact velocities.
As a Postdoctoral Associate at MIT, my current research lies in the development of computational methods for advanced response of materials, conducting simulations and analysis of helmet response to ballistic impact, and validation of the computational framework of Summit.
