Soifer received his Ph.D. in 1973.[1] Soifer has been a professor of mathematics at the University of Colorado since 1979. He was visiting fellow at Princeton University 2002–2004, and again 2006–2007. Soifer also teaches courses on art history and European cinema. His publications include 13 books and over 400 articles.

Every spring, Soifer, along with other mathematician colleagues, sponsors the Colorado Mathematical Olympiad (CMO) at the University of Colorado Colorado Springs. Soifer compiles and writes most of the problems for the contest. The CMO was founded by Soifer on April 18, 1983 (

For the Olympiad’s 30th anniversary, the University produced a film about it: In May 2018, In recognition of 35 years of leadership, the judges and winners decided in 2018 to rename the Colorado Mathematical Olympiad to the Soifer Mathematical Olympiad.

In 1991 Soifer founded the research quarterly Geombinatorics, and publishes it with the Editorial Board, which includes Ronald L. Graham, Jaroslav Nešetřil, Branko Grünbaum, Heiko Harborth, Peter D. Johnson Jr., Geoffrey Exoo, and János Pach. Paul Erdős was also an editor. (

In July 2006 at the University of Cambridge, Alexander Soifer was presented with the Paul Erdős Award by the World Federation of National Mathematics Competitions.

Soifer is currently the President of the World Federation of National Mathematics Competitions ( Soifer's Erdős number is 1.

Soifer's current projects include new publications and new expanded editions through scientific publisher, Springer of previously published books, "Mathematics as Problem Solving," "How does one cut a triangle?," "Geometric Etudes in Combinatorial Mathematics," and "Colorado Mathematical Olympiad: The First Ten Years and Further Explorations." The latter aforementioned title is expected to be expanded to cover twenty years of the Colorado Mathematical Olympiad, which is currently in its 35th year running.

Soifer is the father of four children, Mark Soifer, Julia Soifer, Isabelle Soifer and Leon Soifer.

Geombinatorics is a quarterly scientific journal of mathematics. It was established by editor-in-chief Alexander Soifer in 1991 and is published by the University of Colorado at Colorado Springs. The journal covers problems in discrete, convex, and combinatorial geometry, as well as related areas. The journal is indexed in Zentralblatt MATH,[2] Excellence Research Australia, and MathSciNet.[3]
