PhD Mechanical Engineer | Nanoindentation, FEA & Materials Testing Specialist

Profile Summary

Mechanical engineer and materials scientist with a PhD from Georgia Institute of Technology, currently a Postdoctoral Research Fellow in the Mechanical Behavior of Materials Group at the University of Kassel, Germany. My research focuses on nanoindentation and high-strain-rate mechanical testing, with custom Python pipelines for analyzing instrumented indentation data. Technical expertise: nanoindentation (Alemnis, KLA iMicro, Agilent G200), SEM, AFM, FEA (ABAQUS/ANSYS), CAD/CAM (SolidWorks, CATIA, NX, Creo, Inventor), and Python-based data analysis. Previously Head of Department and Dean of Engineering at the Air Force Institute of Technology (AFIT), Nigeria, where I led two TETFUND-funded research grants as Principal Investigator and supervised graduate students. BS/MS from Drexel University, PhD from Georgia Tech. I offer freelance support in materials characterization, mechanical testing data analysis, FEA simulation, CAD design, and technical/academic writing.
