Koos Verhoeff

Emeritus Professor of Computer Science
Koos Verhoeff, retired Full Professor of Computer Science at the Erasumus University Rotterdam, The Netherlands,
has designed and constructed mathematical art since the early 1980s.
He mainly designs 3D sculptures, constructed in wood, bronze, aluminum, stainless steel, and plastics, often involving mitered beams.
He has described himself as more of an explorer and a discoverer than a designer.
He wonders and wanders about the abstract world of mathematical structures, looking for forms with intriguing mathematical properties as well as aesthetic appeal.
