Applied Physicist | Electro-Optical & RF Systems Expert | Nanotechnology & Sensor Development

Profile Summary

I am a PhD-trained applied physicist with over 17 years of experience bridging defense, aerospace, and nanotechnology research. My work has focused on electro-optical (EO/IR) systems, RF sensors, nanomaterials, and biosensing platforms, combining deep technical understanding with hands-on prototyping and laboratory leadership. I have led projects involving EO/IR design, nanotechnology and wireless communication systems, and magnetic nanostructure-based sensors, working in both industrial and academic environments. My experience spans cleanroom nanofabrication, signal processing, and instrumentation automation (LabView, Python). I bring a multidisciplinary background that combines applied physics, engineering, and materials science, enabling me to connect specialists from different domains. I enjoy helping diverse teams collaborate effectively and translate complex technical ideas into practical results. Whether you need help troubleshooting complex instrumentation, designing experiments, or translating R&D results into publications, I provide precise, data-driven support grounded in real lab experience.
