About Me

I am a PhD scholar in the Department of Metallurgical and Materials Engineering at the Indian Institute of Technology Madras, Chennai, India. Currently, I am working with Prof. Anand K. Kanjarla (Dept. of MME) and Prof. Sundararajan Natarajan (Dept. of ME). I have a passion for mathematics and programming, which drives my enthusiasm for computational mechanics. My current research explores phase-field modelling of fracture in polycrystals and its implementation using the scaled boundary finite element method.

Research Interests

• Scaled boundary finite element method
• Phase-field modelling of damage
• Crystal plasticity
