My father, Hoshyar Nooshin, who has died aged 90, was a pioneering figure in the field of spatial structures and director of the University of Surrey’s Spatial Structures Research Centre for 28 years.
Hoshyar taught at Surrey University from its foundation in 1966, having joined its predecessor, the Battersea College of Technology, as a lecturer in 1963. There he became renowned for his research into computer-aided design and as the originator of Formex algebra, a branch of mathematics that developed a set of interactive algorithms used to create complex structures. He also played a key role in creating the programming language Formian.
