Professor of Architecture and Gerontolgy Victor Regnier (Ruh-NEAR) teaches at the University of Southern California. In 1997 he published a book (Assisted Living Housing for the Elderly: Design Innovations from the United States and Europe” (Wiley) comparing the Northern European and U.S. approaches to caring for the elderly. The European model helps the elderly to stay in their homes, with the help of assisted living programs. This week he is presenting a paper on the subject at the AIA (American Institute of Architects) convention in Philadelphia.
