Chiara Romanengo
I earned my Ph.D. in Mathematics and Applications at the University of Genoa in collaboration with CNR-IMATI, where I specialized in mathematical methods for the analysis of 3D shapes. My doctoral research focused on recognizing and representing geometric features on 3D models using the Hough transform. I previously obtained a Master's degree in Mathematics, also at the University of Genoa, graduating with a thesis on curve detection in 3D objects through the same technique. For further details, see my personal page: https://chiara-romanengo.webnode.it/
Research Activity
My research focuses on geometric modeling, shape analysis and the recognition of features on the surface of 3D models, to which I assign a mathematical representation.
The techniques I have developed are applied in various fields, including cultural heritage, CAD, and digital twins for urban contexts.
