Noam Aigerman (pronounced "Noh-uhm", like Noah with an M at the end.)
Associate Professor, University of Montreal
Associate Academic Member, Mila


I work on problems related to machine learning and 3D geometry. Namely, my research lies at the intersection of geometry processing, deep learning, and optimization, with applications in 3D vision and computer graphics.
Currently, I mostly focus on using geometry processing to devise theoretically-grounded machine learning approaches for 3D problems; and, vice-versa, approaching geometry processing tasks from a machine learning perspective.
Yes, this is I!
