Karthikeyan Rajan

My academic background, including a Ph.D. in Materials Science from Shizuoka University, has equipped me with a deep understanding of material properties, structural analysis, and the latest advancements in characterization technologies.

In my current role at Accelera by Cummins, I have honed my skills in advanced materials characterization, employing techniques such as Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), and Atomic Force Microscopy (AFM) to analyze material properties and performance. My work has involved designing and conducting experiments, interpreting complex data, and providing actionable insights to drive project success. A particular highlight was leading a project that optimized the bipolar plater materials properties for alternative energy generation, resulting in a 20% improvement in its durability and performance.

With a robust background in Materials Engineering and a proven track record in leading projects related to design, test execution, data analysis, and laboratory management, I am confident in my ability to contribute effectively to a team and drive forward innovative engineering solutions.
