About

I am a materials researcher specializing in advanced composite materials, additive manufacturing, and solid-state processing techniques for structural and biomedical applications. My research focuses on developing sustainable, high-performance composites through innovative reinforcement strategies, process optimization, and microstructural engineering. My work integrates experimental fabrication (FDM, friction stir welding, powder metallurgy, squeeze casting, hot pressing), microstructural characterization (OM, SEM, XRD), and statistical optimization tools such as Response Surface Methodology (RSM), Taguchi methods, ANOVA, and Genetic Algorithms. I have extensive experience in: Polymer matrix composites for biomedical and tribological applications, Aluminum and magnesium matrix composites reinforced with ceramic and industrial/agro-waste particles, Friction stir welding of dissimilar alloys with particle incorporation, Wear behavior and mechanical performance evaluation, Sustainable materials development using recycled polymers and industrial waste. My research aims to bridge sustainability, performance optimization, and real-world engineering applications.
