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 testing of novel fiber optic sensors for the measurement of physical, chemical and biological parameters. I am mainly involved on: fabrication of long period gratings (LPG) in specialty optical fibers and their sensing applications; investigation of fiber optic sensors under different ionizing radiations; development of fiber based bio-chemical sensors for medical and industrial applications; environmental and structural monitoring. Main technologies involved: fiber Bragg grating (FBG), LPG, lossy mode resonance (LMR), localized surface plasmon resonance (LSPR), 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.
