PhD Mechanical Engineer | AI & Digital Twin in Materials Science | LCA & Techno-Economic Analysis Specialist

Profile Summary

I am a PhD-qualified Mechanical Engineer with extensive expertise in AI integration for materials science, digital twin development, and life cycle assessment (LCA). My research spans the optimization of aluminum metal matrix composites reinforced with agro-marine waste, combining advanced characterization techniques (SEM, EDS, XRD) with statistical modeling, techno-economic analysis, and sustainability metrics to achieve superior performance and cost-effectiveness. With a strong publication record in Q1 peer-reviewed journals, I have led and contributed to projects that merge machine learning, computational modeling, and experimental validation to drive innovation in manufacturing, energy efficiency, and environmental impact reduction. My work also involves multi-criteria decision analysis, finite element simulation, and process optimization for industrial applications. In addition to my academic achievements, I have practical experience in the oil and gas sector, where I applied engineering principles to high-precision, safety-critical operations. I am adept at interdisciplinary collaboration, translating complex technical data into actionable solutions for industries such as energy, environmental engineering, and manufacturing. I am passionate about leveraging advanced technologies and sustainability frameworks to create materials and systems that are economically viable, environmentally responsible, and industrially scalable.
