Flavio Esposito

Welcome to my personal webpage. I'm an Assistant Professor Tenure-track (RTDb) of Eletronics (IINF-01/A) at the Department of Engineering, University of Naples "Parthenope" (Italy).

My research activity is focused on the design, simulation, fabrication, and characterization of innovative fiber optic sensors for the measurement of physical, chemical, and biological parameters. I am mainly involved in: development of fiber sensors for ionizing radiation environments (medical and industrial applications); biosensing based on different technologies for the detection of various biomarkers and analytes; biofilm monitoring; and chemical sensing for volatile and flammable compounds. My work also includes the design and fabrication of sensors in advanced fibers featuring exotic dopants, microstructured and nanostructured geometries, and nanoparticle doping.

Main technologies involved: Long Period Gratings (LPG), Localized Surface Plasmon Resonance (LSPR), Lossy Mode Resonance (LMR), and fiber interferometers.

I received the outstanding reviewer award from Sensors (2019), IEEE Sensors Journal (2020) and IEEE Photonics Technology Letters (2023). I am editorial board member of Sensors, Photonics and Biosensors; I am serving as Associate Editor for IEEE Sensors Letters and IEEE Sensors Reviews. 

Here you can find my publication list and curriculum vitae.

Please do not hesitate to contact me for collaboration.
