Hangai Prize Medal

Hangai Prize Recipients

The Hangai Prize was established in 2001 in memory of Professor Yasuhiko Hangai (Japan, 1942-1998), a very active member of the IASS and its Executive Council.  In accordance with Professor Hangai's career-long encouragement for young people, the award recognizes young talented researchers, designers, and engineers working in the field of shell and spatial structures whose papers submitted to the annual IASS Symposium are judged to be most meritorious by the Hangai Prize Committee.

Below are the listings of past winners with the titles of their papers, each of which has been published in the Journal of the IASS following the respective conferral.  To browse photos of the conferral ceremonies and of the past winners, visit this site.
