Victor Ginzburg (in some 1980s articles spelled Ginsburg) is a professor of mathematics at the University of Chicago. His thesis in Moscow was under Alexandre Kirillov. His main interests are representation theory, especially geometric representation theory, including more recently noncommutative algebraic geometry.
Warning: there is another mathematician (global analysis, symplectic geometry), Viktor Ginzburg (note the English spelling).
