Summary
My professional background encompasses three significant phases. I am a researcher skilled in the development of fiber-optic sensors for industrial applications and electrical noses. Areas of interest are sensors and instrumentation for applications in harsh environments, femtosecond laser machining and characterization of micro/nanostructures, and the development of novel optical/microwave photonic sensors and systems. I also engaged in the New Sciences and Technologies center, focusing on the design of mice and nano gas sensors using lithography and MEMS and NEMS methods. Subsequently, during my tenure at the Nano Research Center in Australia, I contributed to the development of solar cells and fuel cells by using nanofibers and mesoporous semiconductors.
