Profile Summary

I am a PhD physicist with 10+ years of experience in materials science and optical materials research, specializing in experimental design, data analysis, and advanced characterization techniques. My expertise includes a wide range of analytical instruments and material characterization methods, including microscopy (optical, electron), optometry, metrology, and spectroscopy. I am highly skilled in designing and optimizing experiments, interpreting complex datasets, and delivering clear, actionable insights. I’ve contributed to academic and applied R&D projects involving the development and analysis of advanced materials, with a strong focus on quantitative image processing, data visualization, and scientific reporting. My toolkit includes Python, MATLAB, ImageJ/Fiji, and statistical analysis methods tailored to physical and optical materials. Whether you're looking for expert support in experimental planning, image/data interpretation, or scientific consulting, I bring precision, clarity, and efficiency to every project. Let’s connect to explore how I can support your research or development goals.
