Professional Background

B.Sc ECE-Math, Ben Gurion University, Israel, 2007; M.Sc. ECE,  Ben Gurion University, Israel, 2008; Ph.D Applied Math and Computer Science, Weizmann Institute of Science, Israel, 2016; Postdoctoral positions: Weizmann Institute of Science, 2016, Duke University, 2016-2020.

Research Synopsis

My research focuses on numerical optimization, applied geometry, computer graphics, vision and machine learning, with applications to the sciences and engineering. I am particularly interested in problems involving, in a very broad sense, optimization and geometry: various aspects of shape representation, processing, manipulation, analysis and comparison, but also problems pertaining to the geometrical properties of general signals and data; my passion is in constructing and analyzing algorithms for dealing with ''real-world'' data and problems.
