Shifi (Shifra) Reif

My main research interests are Representation theory, Lie algebras and superalgebras, and algebraic combinatorics. I am currently at a tenure track position at Bar Ilan University. I’ve been a postdoctoral fellow at University of Michigan 2011-2015, after receiving my Ph.D. at the Weizmann Institute of Science, where my advisor was Maria Gorelik.
