Alexander Jurjewitsch Soifer ( Russian Александр Юрьевич Сойфер ; born  August 14, 1948 in Moscow ) is a Russian-American mathematician who deals with group theory, geometry and combinatorics .

Soifer graduated from Moscow State Pedagogical University in 1971 , where he received his doctorate from Leonid Kulikow (and Paul Erdős ) in 1973 ( Abelian Groups Having Minimal Systems of Generators ). He has been a professor of mathematics at the University of Colorado since 1979 , where he also teaches art and film history. Among other things, he was visiting scholar at DIMACS (Center of Discrete Mathematics and Theoretical Computer Science, Rutgers University ) and Princeton University (2002 to 2004, 2006/2007).

From 1996 to 2005 he was on the committee for US participation in the International Mathematical Olympiad (as was also the jury of the national mathematical Olympiad of the Soviet Union 1970 to 1974) and himself the founder (1983) of a mathematics competition for schoolchildren, the Colorado Mathematical Olympiad. He has been Secretary of the World Federation of National Mathematics Competitions (WFNMC) since 1996 and its Senior Vice President since 2008.

He is the author of several books on mathematical problem solving and, for example, on coloring problems in combinatorics.

In 2006 he received the Paul Erdös Prize of the WFNMC. He is the founder (1991) and editor of the quarterly journal Geombinatorics, a research journal on open problems in combinatorics and discrete geometry.
