‌Geometry is not only an important branch of mathematics, it is also a source of beauty and plays a role in many applications. I am particularly intrigued by the high aesthetics of shapes which result as solutions of geometric problems and by seeing geometry materialized through novel fabrication techniques. This materialization becomes most prominent in architecture. It motivated our research in Architectural Geometry, which had an impact both on the geometric theory and on the realization of complex geometry in contemporary architecture.
