My research focuses on the development of advanced finite element methods (FEM) for simulating complex engineering systems governed by the coupled interaction of multiple physical fields — including structural mechanics, fluid dynamics, thermal effects, and electrostatics. A central theme across my work is the monolithic approach to multi-physics simulation, wherein all governing equations and interface conditions are solved simultaneously, yielding formulations that are more robust, accurate, and physically consistent than conventional partitioned approaches.
Development of monolithic finite element methods for simulating coupled fluid and structural systems, including compressible and incompressible flows, floating body dynamics, and free-surface problems. Applications include offshore structures, hydraulic systems, and biomedical devices.
Finite element modeling of micro-electro-mechanical systems (MEMS) involving the simultaneous interaction of structural deformation, viscous fluid flow, and electrostatic fields. Relevant to the design of sensors, actuators, resonators, and energy harvesters.
Design and implementation of stable, energy-consistent, and geometrically nonlinear finite element formulations, including Arbitrary Lagrangian–Eulerian (ALE) methods, mortar-based interface treatments.
Computational modeling of the nonlinear dynamic interaction between pantograph current collectors and overhead contact wire networks, with application to high-speed electrified railways and current collection quality assessment.
Analytical and numerical methods for thermoelastic problems in solids, with emphasis on stress-focusing phenomena in cylindrical and spherical geometries under extreme thermal loading. Relevant to nuclear engineering and high-temperature structural applications.
