Research Interest

Nonlinear differential equations with industrial applications; Modeling, numerical simulations, finite element analysis, symbolic computation, application of simulation software; Stability and integrity of structures of advanced materials with applications in energy and bio-medical engineering, MEMS and NEMS; Non-Newtonian flows and polymer extrusion; Interdisciplinary research; Actuarial mathematics.

The nonlinear differential equations arise from nonlinear material constitutive equations and the continuum mechanics of solids and fluids. For numerical simulations and analysis, lumped parameter models; asymptotic and perturbation methods, finite element and finite difference methods, symbolic and numerical computation software (Matlab, Methamtica, Ansys, Comsol, Maple, and Abaqus) are developed and integrated with synergistic and interdisciplinary research collaborations. For industries, my research interests are in three application areas: 1) Developing novel optimal design methodology, design equations, and algorithms for design of polymer thin sheets and coating die interior geometric flow channels; 2) Optimal design of resonators for Microelectromechanical systems (MEMS) using advanced materials such as graphene and heat-treated metals; and 3) Stability of aerospace and energy structures made of advanced materials with built-in internal shear rate dependency damping, such as metal rubber and INVAR.
