  • Phillip Griffiths Assistant Research Professor
  • 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.
