Or Shalom
I am a mathematician at the department of mathematics at Bar Ilan University. Before that I was a member at the Institute of Advanced studies at Princeton and a PhD student at the Einstein Institute of Mathematics (HUJI) under the supervision of Professor Tamar Ziegler. My research interests lie primarily in Ergodic theory, Ergodic Ramsey theory and Additive Combinatorics. You may reach me at Or.Shalom@math.biu.ac.il.
