Applied Research & Engineering Specialist | Experimental Data Analysis | Sensors, Materials & Electronics

Profile Summary

I am an applied research and engineering specialist with a background in mechatronics and research experience in sensor design, printed electronics, and functional materials. My work focuses on the design, testing, and performance evaluation of physical and electrochemical sensors, including experimental validation under real operating conditions. I support research and R&D teams by analyzing experimental data and translating measurement results into clear technical conclusions and practical recommendations. I have experience in designing experiments (DoE), analyzing electrical, mechanical, and electrochemical data, and preparing technical reports, publications, and research documentation. My work is typically interdisciplinary, spanning materials, electronics, mechanics, and chemistry. I work with Python-based analysis, Origin, and spreadsheet tools, selecting methods and software according to project needs, with a strong focus on engineering reasoning and data interpretation rather than purely computational processing. I am available for remote, part-time consulting, short analytical projects, and applied research support for academic and industrial clients.
