David Bayer, Professor Emeritus of Mathematics and a former Chair of the Department of Mathematics, began teaching at Barnard in 1987, and became a full-time faculty member in 1990. His teaching specialties include linear algebra, modern algebra, and combinatorics.
Professor Bayer served as mathematics consultant, hand double, and day player in A Beautiful Mind, the 2001 feature film based on the life of Nobel laureate John Forbes Nash, Jr.
Professor Bayer is the coauthor (with Mike Stillman) of Macaulay, a computer algebra system for computations in algebraic geometry and commutative algebra. This software uses Grobner basis methods for manipulating systems of polynomial equations.
Professor Bayer holds a U.S. Patent (with N. Karmarkar and J. Lagarias) for a method and apparatus for optimizing system operational parameters.
