Dror Bar-Natan

Dror Bar - Natan ( born January 30, 1966 in Israel) is an Israeli- American mathematician who deals with knot theory and low -dimensional topology.

Bar - Natan studied mathematics at the University of Tel Aviv ( bachelor's degree, 1984) and interrupted by military service ( as a mathematics teacher ) in 1987 at Princeton University, where he in 1991 received his doctorate with Edward Witten in Mathematics ( Perturbative Aspects of the Chern - Simons Topological Quantum Field Theory), as a post - graduate student, he was from 1991 to 1995 Benjamin Peirce Assistant Professor at Harvard University. After that, he was a Senior Lecturer at the Hebrew University in Jerusalem, and from 2002 Associate Professor and from 2006 professor at the University of Toronto. 1999/2000 he was Visiting Professor ( Visiting Miller Professor ) at the University of California, Berkeley and at MSRI.

Bar Natan dealt among other things with topological quantum field theory, especially the Chern - Simons theory and the use thereof for the production of knot invariants ( first recognized by Edward Witten): he proved that this topological quantum field theory gives knot invariants in each order of perturbation theory. He dealt with Vassiliev knot invariants - and Khovanov homology, to which he made ​​major contributions.

He criticized other the Bible Code by Michael Drosnin, by showing that these methods can find any messages from the Bible as well as in other works such as Tolstoy's War and Peace.

Bar - Natan is co-editor of Compositio Mathematica. It has both the Israeli and the American citizen.
