Frank-Olaf Schreyer is a German mathematician, specializing in algebraic geometry and algorithmic algebraic geometry.
Schreyer received in 1983 his PhD from Brandeis University with thesis "Syzgies of Curves with Special Pencils" under the supervision of David Eisenbud. Schreyer was a professor at University of Bayreuth and is since 2002 a professor at Saarland University.
He is involved in the development of (algorithmic) algebraic geometry advanced by David Eisenbud. Much of Schreyer's research deals with syzygy theory and the development of algorithms for the calculation of syzygies.
In 2010 he was an invited speaker (jointly with David Eisenbud) at the International Congress of Mathematicians in Hyderabad. In 2012 he was elected a Fellow of the American Mathematical Society.
