Sonia Martín López

Sonia Martín López is an Associate Professor in the Department of Electronics Technology at the Universidad de Alcalá, Spain. She leads the GRIFO (Photonics Engineering Group) research team and is the Researcher in Charge of the CSIC (Spanish National Research Council) Associate Unit of Sensors and Photonic Technology. Her expertise lies in advanced photonics and optical fiber sensing technologies, with a focus on distributed sensing systems for structural, environmental, and geophysical applications.

Educated at the Universidad Complutense de Madrid, she earned a PhD in 2006 with a thesis on optical fiber supercontinuum generation. Her research emphasizes innovations in phase-sensitive OTDR (optical time-domain reflectometry), dual-comb spectroscopy, and high-resolution fiber optic sensing for applications like seismic monitoring, underwater acoustics, and climate change observation.

Her recent work includes breakthroughs in time-expanded sensing techniques, submarine fiber networks for climate studies, and sensor systems for infrastructure integrity. Sonia actively contributes to international collaborations, leveraging optical fiber infrastructure to address global environmental and engineering challenges.

Her lab, GRIFO, develops cutting-edge technologies such as millimeter-resolution fiber sensors and hybrid machine learning models for threat detection in smart surveillance systems. Her publications span high-impact journals and conferences, focusing on advancing the stability, resolution, and applicability of fiber optic sensing methods.
