Dr Luca Zanotti Fragonara is Lecturer in the Centre of Autonomous and Cyber-Physical Systems and in the Aerospace Integration Research Centre. He is director of the Applied Artificial Intelligence MSc course since 2019.
His research is focused on machine learning for structural health monitoring, deep learning and system identification. He is involved in a series of high-impact research projects ranging from autonomous inspections of aerospace structures to structural health monitoring for increasing the resilience of industrial plants.
He matured a wide and unique experience working in monitoring problems applied to civil, mechanical, aerospace and space structures. Moreover, his interests in machine learning allowed him to expand his research activities to other areas, such as perception using camera vision systems, lidars, estimation and sensor fusion.
He also carried out research in the area of non-linear dynamics and finite element modelling.

My wide interests are in deep learning and validation of deep learning models, Structural Health Monitoring of Civil, Mechanical and Aerospace structures, Non-linear dynamics, Finite Element modeling and statistical signal processing.
I am involved in MSc students’ supervision during their final thesis, in teaching activities, and research project management activities.
