Nadav Dym

I am an Assistant Research Professor at the Department of Mathematics of Duke University, hosted by Prof. Ingrid Daubechies at the Information Initiative at Duke (iiD).
In 2018 I completed my PhD in the Department of Computer Science and Applied Mathematics at the Weizmann Institute of Science under the supervision of Prof. Yaron Lipman.
My research focuses on developing and analyzing algorithms for geometric problems arrising in computer graphics and vision, medical imaging and related fields, using mathematical tools from various disciplines such as differential geometry, optimization, and functional analysis.
