Research interests

• Physics-based computational modeling of coupled liquid-powder-gas dynamics in metal additive manufacturing: Focus on modeling of melt pool dynamics and powder-gas interaction
• Computational modeling of multi-phase flows: Development and application of cut-element based sharp interface methods and consistent diffuse interface methods using continuous and discontinuous Galerkin schemes for accurately simulating multi-phase fluid dynamics.
• Constitutive modeling of quasi-brittle materials: Advanced modeling of material behavior (e.g., anisotropy, gradient-enhanced damage mechanics, micropolar continua, damage-plasticity, and hypo-plasticity models) for 3D printed concrete, rock, and soils, to predict cracking, shear banding, and other failure mechanisms.
• High Performance Computing: Matrix-free algorithms and large-scale, parallel computing platforms to enhance the efficiency of simulations  (regular contributor to the deal.II library)
