Education

Bar-Natan earned his B.Sc. in mathematics at Tel Aviv University in 1984. After performing his military service as a teacher, he went to study at Princeton University in 1987. He obtained his Ph.D. in mathematics from Princeton in 1991, under the direction of physicist Edward Witten.[1]

Professorship

After holding a Benjamin Peirce Assistant Professorship at Harvard University for four years from 1991–95, he returned to Israel, and became Associate Professor at the Hebrew University of Jerusalem. He moved to the University of Toronto in 2002, and was promoted to Full Professor in 2006.[2]

Personal life

Bar-Natan holds US, Israeli, and Canadian citizenship, and currently resides in Canada. Originally refusing to take the Canadian citizenship oath because it would require him to swear allegiance to royalty,[3] Bar-Natan later decided to become a citizen but publicly announced his intention to renounce the oath immediately after becoming a citizen.[4] He is married to mathematician Yael Karshon and is the father of two sons, Assaf and Itai.[2]

Research

In 1999, Bar-Natan collaborated on a paper with the goal of mathematically refuting claims made in The Bible Code by Michael Drosnin that hidden messages could be deciphered from within the bible. In particular, the paper demonstrated that practically any "code" could be found within the Bible, thereby debunking Drosnin's "discovery" of specific codes. This work is outside the main scope of his academic interests, although he is known for it because of the popularity of The Bible Code.[5]

Academically, Bar-Natan has made significant contributions to the formalization of Khovanov homology.

Bar-Natan was a member of the Editorial Board for the journal Compositio Mathematica for 10 years, until 2010.[2]
