Barak Sober
Assistant Research Professor of Mathematics

I am currently privilaged to be working with Prof. Ingrid Daubechies . Before that, I have completed my PhD in applied mathematics at Tel-Aviv University under the mentoring of Prof. David Levin . My MSc was co-mentored by Prof. Levin and Prof. Israel Finkelstein from the Department of Archaeology and Ancient Near Eastern Civilizations.

My research ranges between analysis of high dimensional data from a geometrical perspective and the application of mathematical and statistical methods in digital humanities.
