Gregory McNeice was a professor in the Department of Civil Engineering at the University of Waterloo from 1968 to 1993.

McNeice’s research interest was in stress analysis, especially in human bones, joints and prostheses. He began investigating scoliosis in 1974 and helped to develop a device called the scoliosis chariot, which was used to keep a patient in one position while being x-rayed. He also helped develop a computer program that would help physicians measure the progress of the disease and a new stainless-steel rod that could be implanted into children’s backs until the spine straightened.[1]

In 1980, McNeice helped create a new floor for the Maple Leaf Gardens in Toronto, Ontario in partnership with Spieth-Anderson Ltd., the manufacturer. The new floor was installed shortly before the 1980 Gymnastics World Cup and was designed to respond to the movements of athletes and cause less orthopedic injury.[2]

This research team received $50,000 a year from the Centre to focus on biomechanics, specifically applying mechanics to implants in the body.[4]
