Assistant Professor at University of Tehran
My professional interest topics are machine learning, computational vision and signal processing. I am particularly interested in mathematical foundation of these fields such as differential geometry, optimization, functional analysis and statistics. My current research themes are: Developing optimization methods on manifolds; Statistical modeling of natural images; Using developed methods in applications like image segmentation, object recognition, etc.
