About Me
I am a PhD scholar in the Department of Metallurgical and Materials Engineering at the Indian Institute of Technology Madras, Chennai, India, working with Prof. Anand K. Kanjarla (MME) and Prof. Sundararajan Natarajan (ME). My research lies in computational mechanics, with a particular interest in developing efficient and scalable computational methods for complex problems in solid mechanics and materials science. My current work focuses on modelling deformation and fracture in polycrystalline materials using the Octree-based Scaled Boundary Finite Element Method (SBFEM).Research Interests
