Keller received in 1990 his PhD from the University of Zurich under Pierre Gabriel with thesis On Derived Categories.[1]

His research is in homological algebra and the representation theory of quivers and finite-dimensional algebras. He has applied triangulated Calabi-Yau categories to the (additive) categorification of cluster algebras. In 2013, he received and honorary degree[2] from the University of Antwerp. In 2014 he received the Sophie Germain Prize. He was an Invited Speaker with a talk On differential graded categories at the International Congress of Mathematicians in Madrid in 2006,[3] and is a fellow of the American Mathematical Society.[4]
