Nicola Giaquinto was born in Bari in September 1966. He obtained his high school diploma in science from the Liceo Scientifico "E. Fermi" in Bari (1985, with honors) and a degree in Electronic Engineering (1992, with honors) from the Polytechnic University of Bari, where he then obtained his PhD (1997).

Since 1992, he has been conducting research and teaching in the Electrical and Electronic Measurements group at the Polytechnic University of Bari, and since the same year he has been a member of the Italian Association GMEE (Electrical and Electronic Measurements Group).

He was the Rector's Delegate for International Relations from December 2013 to October 2021 and a member of the Academic Senate from 2019 to 2021. He has been Full Professor of Measurements since 2021.

His research interests include measurement uncertainty, signal processing for metrology, remote sensing, distributed and intelligent measurement systems, and quantitative methods for biomedical and environmental monitoring. His most recent research focuses on quantifying uncertainty in model- or artificial intelligence-assisted measurements, with applications ranging from time-domain reflectometry to Earth observation.

He actively participates in national and international research networks, including the IEEE Instrumentation and Measurement Society, and contributes to editorial and organizational activities in conferences and scientific journals in the field of measurement.
