Barak Sober
Phillip Griffiths Assistant Research Professor
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.
