Arash (Ali) Mahdavi-Amiri

I am an assistant professor in the School of Computing Science, Simon Fraser University, the director of Master of Science in Professional Computer Science, and the Vice President Research at MARZ. I lead and manage several industrial and research projects related to Computer Vision, Machine Learning, and Computational Fabrication. My main research interest is Computer Graphics with specialty in Geometric Modeling, Digital Fabrication, Machine Learning, and Computer Vision.

I have received several awards including Early Career Researcher Award, NSERC Postdoctoral Fellowship, J.B. Hyne Research Innovation Award, Michael A. J. Sweeney Award, and Teaching Excellence Award.

I am also an associate editor of IEEE Transactions on Visualization and Computer Graphics and Elsevier, Computers & Graphics. In addition, I have served the community by being the program chair of 3DV 2026, general chair of GI 2021, and local chair of IGS 2019.
